Terrible customer service not interested in comply...

Terrible customer service not interested in complying with consumer law. Bought a dishwasher and stopped working after 10 uses. Manufacturers tried twice to repair and failed. Marks Electrical don't return calls and ignore letters of complaint. Refer you back to manufacturer who refer you back to Marks Electrical. Been without a dishwasher now since 3rd December and still no idea when it will be repaired or replaced. Had I read all the reviews on Google would never have purchased from this atrocious company.
22nd December - up date
Don't be fooled by Marks Electrical quick replies to their terrible reviews. It's still the same contempt for customers failing to reply to emails or phone calls despite their comments.
If they put as much time and effort into dealing with their actual customers as they do into replying to Google reviews they might find the online comments improve.
The manufacturer wants a third go at repairing a not fit for purpose dishwasher 24 days after the problem first reported. SHOP ELSEWHERE
