1stopbedrooms Won't repair broken new couch; won't refund my money NYC NY

The sold me a sleeper couch & I also purchased a 5 year warrantee. The sleeper couch mechanism is broken and every time I contact them to fix it they tell me the part won't come in for another month. This has been going on for what will be the 4th month. There is a senior man in the apartmen. His caregiver cannot sleep on the floor.

1Stopbedroom keeps lying to me and each time has given me misinformation and a further postponement. I want to return the couch and get q full refund but it would cost me half of what I paid for the couch. I am on social security. This is very difficult as I do not have money to replace it by buying a new couch. I sent them pictures and they said only a part needed to be replaced but they won't send it & won't refund my money.
