Nope, been onto trading standards via the citizens advice bureau. Spoke to my credit card company about a chargeback and they're sending me some paperwork to fIll in to show the mileage discrepancy on the hpi, also the finance still on the car and the fact it was still advertised for sale after the deposit had been taken.
I did offer to just have £150 back more as a goodwill gesture as hes seems to think I've been wasting his time lol but he's ignoring my emails now so il do it through the appropriate channels and see what comes of it. Had a quote for the cambelt and other bits, well over 500 so maybe it was a good thing. 200 quid is better then over 500
