Duped by carpet cleaner

Sent a large for general cleaning that had 2 white residue marks from me cleaning stains It came back to me with 2 brown marks. They convinced me it was a reaction with what I did and their solution or that my solution got washed out and brought my stain to the surface. I thought it was weird ( have cleaned a few stains in my 60 years) but they were the pros. So I agreed to their 700$ which I thought was an awful lot but was in a bind since I have another carpet like it that matches and bought from ElTE so not cheap. It came back with NOW 3 brown marks. Karen said o we would never send a carpet out like that something must have happened from the time we cleaned it to the time you received it. When I tried to explain to them that those stains which I sent it to you with in the first place after you cleaned the carpet was the same thing and youre charging me for it!!! They ghosted me!!! They sent an outside rug cleaning company to get the brown marks out and then just charged my card. When I tried to explain to them the brown marks were not my original marks they just ghosted me!! I have had carpets cleaned by them in the past with no problems but if something happens they Dont stand behind their work!! They get their back up and find ways to justify what has happened in their favour There are plenty of other carpet cleaning places that do just as good a job and dont treat their customers in this way. haha like the one they sent to clean my stains Dr rug or herrats which offer the same service This is a perfect example of all talk through advertising!! In all seriousness folks you can get a million 5 star reviews but its how you handle it when something happens!!!!!! Which dictates true 5 star business
