Rip off merchants!

I have a Fiat Panda Dynamic, which decided one day that it didn't want to reverse anymore. The car would go into gear but when trying to reverse the rear of the car would rise and stay put. It would go forwards after sticking a bit but any attempt to reverse failed.
I called the garage to see if they could take a look at the car, as I am fairly new to the area and just wanted to get the nearest garage. They said to bring the car to the garage and they would see what the problem was - it was a free inspection, unfortunately there was a car parked directly in front of mine, so there was no space to manoeuvre out and get the car to the garage. I phoned ATS up and asked if they could send someone out to have a look at the car and maybe get it moving so that we could get it to the garage. After about an hour two mechanics showed up to have a look at the car, one of the guys got into the car, tried to reverse & couldn't so the other guy got underneath the rear of the car & smacked the inner wheel with a hammer (!) They didn't explain whether this was to try and unstick the wheel, brakes or whatever, this guy just hit the wheel to do something. After a while of attacking my car the mechanic decided it was best to just rev the engine as much as possible to skid the car backwards so that there was enough manoeuvring space - probably doing a fair amount of damage to the tyre.
With the car eventually in the garage I got a phone call saying "Basically the whole rear brake system has collapsed, it's all bent which is why the brakes were getting stuck, you need 2 new front tyres and the front brake pads need replacing - it'll be £488."
After a mini heart attack I told them I couldn't possibly afford that so they said "Well, we could probably do it for £380 instead" - still couldn't afford it. I then decided to ring up a mechanic that I knew & had known for years (unfortunately he lived about 300 miles away). I told him what they said & his response was "Have a look on ebay to see how much the parts you need are" Guess what, the parts came to no where near what they had quoted me, even with labour costs added!
I decided to take my car to another garage for a second opinion and upon telling ATS that I was taking my car away was told that I would need to pay a £30 inspection charge before taking my car away, despite being told it was FREE at the beginning of this whole process. When I got to the garage they acted like nothing had happened, there was no mention of an inspection charge & they let me take my car away with no hassle.
Unfortunately for them, the garage that I took my car to next were very honest with me and told me immediately after looking at my car that the car was not nearly as bad as ATS had made out - 1 tyre needed replacing, my front brake pads looked BRAND NEW and it was only one side of the rear brake system that had broken. £200 was quoted to fix these problems, it took them about half a day to fix it & the mechanics at the new garage were the nicest guys you could meet.
Unfortunately I can only assume that because I am a young female they thought they could take advantage.

ATS Euromaster will try to rip you off - DO NOT USE THEM.
