Wrong v belt repairs

<p>I took in my cars for a check and Toyota did diagnostics and said I need to replace the v belt and shocks, I ordered the parts and they arrived 3 days later so I took in my car to the garage on the 21st Feb 2017,so on the 24th I went to take my car but there was a excruciating sound when changing gears , so I took back the car to the garage and the mechanic checked and heard the sound and he said the problem is the v belt they fitted as it was not the same as the old damaged one that is why there is the sound coming out so I left the car again but the service advisor said I need to pay for the new belt but I refused as I have paid for the belt,so on the 24 th the advisor called and said they will get another belt however they were now blaming the air compressor saying it is not a genuine Toyota parts, but my argument is that when they were putting the belt why didn't they call me to get clarification now they say the compressor is damaging the belt yet the belt that was there was working properly.I want Toyota Hatfield to take full responsibility of their mistakes and fix my car because even today that sound is still there and or otherwise they put back the old belt and refund me back my money,their service is very poor and they fail to take accountability of the wrong repairs on my car.</p>
