Business ProfileforPremium Garage Door Repair

I called Superior Garage ************ at ************ on 01/04/2024. I found the ad on ******* When I called, I explained what the problem was with my garage door and asked for a repairman ASAP, the lady dispatcher said a person would be out within the hour. Then a gentleman called and said he would be here within 30 mins and while I was on the phone with him, another gentleman called and asked me if I still needed service, and if so he would schedule it. I advised him that the service tech had already called and said he was on his way. The male dispatcher seemed confused, but said OK. I immediately called back to find out what was going on and the lady dispatcher assured me that the technician on the way was legit. Soon after, the service guy arrived and checked out my pulley system which was hanging down on 1 side and advised me that it just needed to be tightened which he proceeded to fix. then he told me that I needed to replace the rollers. When I asked how much that would cost he told me $600. I thought that was excessive, (what do I know) but agreed to let him replace them. It took him maybe ***** minutes. I wrote him a check and he posted some stickers on my wall and garage door with the name "premium garage door" with the phone number of ************. I paid by check and he left. The invoice has both names". Premium Garage door" and "Superior garage doors" and 2 other garage door company names. I decided to look up Premium and found all the bad reviews so, I looked up the price of the rollers and you can buy them for $25-30 for 10 rollers. I thought I had hired someone from a reputable company and feel that I was deceived. I have thought about filing fraud charges, but I am not sure what to do. I do not understand how I got the wrong company out here company, Is he somehow cutting in on the other company's business? The service tech that was here said he was the owner EK of EK garage doors which is another name on the invoice.
