Residents in Wales have reported more than a three-month wait for their new bus passes to arrive.
A rehaul of the bus pass scheme in Wales has left a number of pensioners without travel cards only weeks before existing cards were meant to expire.
Transport for Wales is working with the Welsh Government to replace all current bus passes with new concessionary travel cards.
In total 750,000 bus passes will be renewed across Wales, with the company warning it will take "at least" a month for cards to be returned.
But residents who applied for the scheme in September have said they are yet to receive their pass - despite an original application deadline of December 31.
Marilyn Jones, 64, said she applied at the start of September for her bus pass but is yet to receive a new one.
The psychiatric unit nurse from Aberdare said: "It's disgusting to be quite honest with you.
"I've applied twice online, sent them off, phoned them up and heard absolutely nothing off them.
"They still say it's getting printed. I've emailed them as well.
"You never get to speak to people, you have no contact with anybody.
"You check online and you can't get on the website. In the beginning when everyone was applying you could understand that but even now you try and you can't get on there.
"A lot of older people don't know how to do it online and don't have access to a library. It's not fair on the elderly.
"If I have to pay I have to pay, I've tried up to this point but I'm getting nowhere. I've given up with it now."
In September, the website set up to help people renew their concessionary bus passes crashed for 10 days due to "high volumes" of traffic.
Those eligible now have until January 31 to to apply, at which point the existing bus passes will expire.
A temporary grace period has also been added until the end of February to allow those waiting on their card to continue travelling.
It means bus drivers should accept both old and new-style cards for travel.
June Bevan, 64, from Aberdare, said: "I applied for mine and my husband's pass on the same day at the same time and he had his three or four weeks ago.
"I applied when they first asked for applications but I've had nothing back to say it has been received.
"I've been to the library where they are helping people and they said they've had people waiting 11 weeks. I've bypassed that time as well."
Electrical engineer Mark Anderson said his bus pass is now two months overdue after applying before his 60th birthday in October.
Mark, from Aberdare, said: "I went on the site and it said I could apply one month before I was 60. Then it said you couldn't apply until 20 days before so I went back on October 8 and I've heard nothing.
"I haven't had a confirmation or anything. I've gone back once a week to check and it says my details are being checked. I don't know why it takes two months for it to be checked.
"Now it says it wants proof of address but they didn't tell me they wanted proof of address. No-one has contacted me at all.
"I travel on the train and with a card you get a 30% discount so it's costing me quite a bit of money."
So far Transport for Wales has received more than 550,000 applications from across Wales.
They are still receiving thousands of applications every day.
John Voss, 66, from Aberdare, said: "I applied online and the site crashed so I gave it another month to try it again.
"I phoned up again yesterday and they kept me waiting for 15 minutes on the phone. The woman said there's one check to be made.
"I applied in November so fingers crossed I have it before new year."
Chief cxecutive of Transport for Wales , James Price, said: “We’d like to thank everyone who has applied for their new bus card so far.
"Since September we’ve received over 550,000 applications, which includes 25,000 paper applications and there’s been a significant operation behind the scenes to process all the applications as quickly as possible.
"However, there may be people who haven’t applied yet or customers who are still waiting for their new cards to arrive.
"As a result, we are implementing a grace period in the new year and have worked with bus operators to agree a period of two months.
"During this time bus drivers should accept both old and new-style card s for travel.
"It’s important to stress that this period will be temporary and is not an extension of the deadline. Those who wish to continue receiving the travel benefits into 2020 will need to reapply for their new card by January 31 to make sure that we have time to issue a new card before February 29.”
Ken Skates, minister for Economy and Transport, said "The renewal programme has been a huge undertaking and I have been impressed with how Transport for Wales has worked with local authorities and partner organisations.
"Many people eligible for a bus pass are amongst the most vulnerable in our communities.
"While the majority of applications are in, the expiry date is fast approaching and we have agreed an official grace period. This temporary extension will give more time to those who need it, and help alleviate concern for people who haven’t received their new card."
