Dozens of drivers have been hit with parking fines - even though they claim they have parked "perfectly" and paid and displayed.
The £100 charges have come months after then drivers used the car park with more than 100 people impacted by the fines.
Those that have appealed the fines, have instead had them increased and some have even been threatened with debt collectors, Manchester Evening News reports.
A pensioner said she has "lost sleep" due to the worry.
Sandra Fitzsimmons, 71, used the Paradise Mill car park in Bury last December and was slapped with a letter in February saying she hasn't paid.
She emailed Car Park Securities, which owns the site, but says she got no response. She was then sent another letter demanding £170 - and that her case will be passed onto a debt recovery agent.
“This is a very worrying time for me,” she said.
“I’m 71 and not in the greatest of health and now I’m worried. I’m not sleeping because of fear of what is to come from this company.
“Any help will be a blessing as I just haven’t got the strength to fight these people.”
Sandra isn’t the only driver claiming to have fallen victim to the parking company.
Lesley Marsh says her husband used the car park to go Christmas shopping in December. They then received a £100 fine on February 9.
The pair did nothing for two weeks due to having difficulty paying the charge over the phone. They were then sent another letter on February 22 – with the fine increased to £170.
The couple paid the penalty fee as they are moving house and feared it may affect their credit score. Another driver, David Williams, wrote a letter of appeal to the company after receiving a fine.
But after receiving another letter demanding £100, he paid the fee out of fear a debt collection agency would get involved.
Becky Alex also received three parking fines in three days dating back to November 2021. The fines started out as £60 but have now escalated to £100.
Becky challenged one fine with a parking ticket to prove she had paid but claims she heard nothing back. Due to parking at the site a long time ago, she has since thrown the other tickets away.
And Emma Dunning was fined after she parked at the site on December 19. The 34-year-old says she received a fine on February 17 claiming she had not paid.
Her fine has since been cancelled, but she will still need to pay a £15 admin fee.
Car Park Securities have not replied to any contact from the Manchester Evening News.
