A-1 Sewing & Vacuum Center

I took my carpet cleaner to have it checked and was told it needed to have a part replaced and a new belt put on it. I paid for the new belt and took the machine, knowing I was charged for a new belt by a company in Oceanside, Ca called Sew Pro's about a month earlier. I did not use the machine between the time Sew Pro's said they replaced the belt and when A-1 said they replaced the belt.I contacted both company's and said one of them is not telling the truth, the person at A-1 was belligerent and unwilling to discuss the fact that two company's sold me a new belt saying it needed replaced and the machine was not used during the time between being sold and new belt twice.
