Rivercrest Sewing Center Advertise Free estimates, then perform Unauthorized Repairs and charge for them. Crestwood Illinois

I called this place and asked if they charged for estimates on Sewing Machine Repairs. They told me they performed free estimates and they would call when they reached a conclusion about the problem and the cost of repairs. They specifically said that "No work would be perforrmed without authorizationfrom the customer." I dropped off my machine. After  week I hadn't heard from them, so I called the store. I got the answering machine, so I left my name, requested an update on the estimate, and requested a call back. A week later, still no call. I called again. This time I was told that the problem was the timing, they had done a "Tune Up", and I owed $69.95 for the work. I reminded them of their policy about not performing work without authorization. I was told that "This was what was necessary to provide an estimate".  I was stunned, and tried to reason with the man. He simply reiterated that this was necessary to provide an estimate. I called a little while later and requested to speak to the owner. I got the same man, who said he was the owner. I asked what the cost of an estimate was. This time I was told it was $20, and again that no work would be performed without my authorization. I identified myself as the person who had called earlier, and told him that I had not been told ablut the $20 charge. He argued that either he or his only other coworker would have told me about the $20 charge. He finally, (probably sensing that I was not going to just pay and go quietly), said "Just come and get your machine and I won't charge you; but there won't be any warranty". I immediately went and got it.  This is a really shady way to do business. DO NOT DO BUSINESS WITH THESE PEOPLE.
