Eddie Wright car supermarket

Long and the short of it bought a car in January for £16k all good excellent salesman happy with purchase. Forward less than 2 months later issue with car phoned Eddie Wrights took car in to be sorted and got it back a week later and with a nice dent on front wing . Well that's where the customer service came to an abrupt end , after more than a week of calling them and getting fobbed off with we'll phone you back never did I must of phoned them a dozen times . So I gave the RAC a ring who the warranty is with turns out they claimed for a window motor on my warranty which wasn't what my car was in for . The RAC are going to investigate it meanwhile I'm seeking legal advice . As they say buyer beware ??
