Firestone Service Center Ripped me off on a tire Tampa, Florida

I had a hole in one of my tires. First the guy says he can patch it then He comes back and tells me I need four new tires and that they don't patch tires when the tread gets to a certain level. This is not true. My thread wasn't that bad the tires were only a year old, but because I had just moved here and had no where else to go I was forced to buy a brand new tire. So a patch for 30-40 dollars ended up costing me about $200 for a new tire. Do not go to Firestone there answer for everything is just replace the whole thing and charge you an arm and a leg. I absolutely hate this company and hope they go out of business. I hate liars and thieves and that's what this company is. All they want to do is charge you as much money as they can for simple things that can be fixed. All they ever talk about is how bad your car is and that it needs tons of work. And this isn't just this one center they are all like that. The guy told me its company policy to do this with tires.
