A man said he had spent nine months fighting for a £1,600 refund from SCS.
Steven Evans, 54, moved into his home in Hale Village last August and purchased some flooring from his local SCS store in Speke the following month.
Steven said staff were nice and helpful in the store but the problems started to unfold when the flooring came to be fitted in October.

He told the ECHO: "They were very nice in the store, it was fine, and then when it came to be fitted the fitters said the underlay for the downstairs floor wasn't correct.
"They said it's best to speak to the store and change it to something more appropriate, so we spoke to the store and they picked up the underlay and then we purchased more appropriate underlay based on the fitters' and store's recommendation."
After the floor was finished, the company moved onto the upstairs of the property and fitted the carpets.
Steven claims five rolls of underlay for the carpets were not needed during the work as well as other items which he asked for the company to come and collect.
Steven says it took until May for the goods to be picked up from his home and he's spent the last nine months waiting for a refund of around £1,600.
Steven said: "I'm very upset. I'm very disappointed in the store and the chaos that has infringed on my time, I'm a very busy person.
"It's a significant amount of money, that's what I don't get."
He added: "They don't know our financial situation, it could make a big difference to us."
After being contacted by the ECHO, SCS said their customer service team has now resolved the issue.
Steven said he is now awaiting a phone call from the company this weekend before the refund can be processed.
He said: "I do appreciate that the directors have shown a commitment to resolve the issue and it seems once they found out there was an issue they dealt with it.
"I'm very thankful, it's only a pity it took the directors to get involved to resolve the issue."
The ECHO approached SCS but the company declined to comment further.
