Utah Go Green Carpet Cleaning

I tried to get a Groupon coupon. Called the company to ask question, they said, not necessary to get coupon we will match their price. I scheduled appt. They called a day ahead to confirm appt. I called them back that day for instructions. They said carpet cleaning company will be there between 10- 1 on my scheduled day. We waited, waited, waited. Around 2 the afternoon a man by the name Shannon called me and said, the must have messed up with the address. So, I gave him my address.. He scoped the house. My family and I moved all the furniture. He brought in a scrubber with a handle and clean some spots that needed deep cleaning he said.... I left to go back to work while my son was at home with Shannon. I returned 30 mins later. He said it would cost me 500.00 dollars. I said, what? Yes, mam. There's alot that needs to be done. I said, I had already discussed the cost and size of my price with the company. Well, I am the owner and that will be the price. I said, I was told 52.00 dollars and extra for stairs. He said, will there must be a mistake. I gave him the number I called and he said that is not the company , I played the message on speaker and it was the company of the person who called me. He would not leave, gave me a bunch of excuses and I kept telling him to leave in a nice manner. When he left I immediately called the company and come to find out he was a contractor and they were surprise with the amount of money he was going to charge me. I told them for that price you would think I had a murder and blood all over my carpet. I said, there were a few stains but not enough to charge me 500.00 dollars. Crazy. I will never use this company again!!!!
