Worst service!

I purchased an Audi A3 from Suzuki in Bryaston after a week of driving the I realized there are some issue there is a funny noise coming from the engine when you are driving over 60kmph, the sunroof makes such an annoying noise and the back door does not open out side, I spoke to the sales lady who sold me the car Johanna she told me to send the car back to be fixed the mechanic was unable to fix it, she told me she spoke to her manger Reil and the same manager is not answering my call not even calling me back or even responding to my mails I even send emails to Jean-Pierre I have not had any response when will they sort out the car, I am unable to drive the new car I got from them a month ago and they keep on dodging me, their level of service is so pour they don't care about their client after the purchase, I hope no one makes the same mistake of buy a car from this dealer, this was my greatest regret buying from this dealer, they don't even care about the reputation of their company!
