Poor service

Dear Sir,I have purchased a Golf 7 GTi in June 2015.After taking delivery of the car, I reported to the sales manager my disappointment with the PDI that was done on the car. I checked the windscreen water, only to find the windscreen washer bottle empty with no water at all and the back seats carpets and back boards were very dusty and dirty. It really looked untidy as though, the car was not cleaned for a while. The sales manager was supposed to get back to me. To date nothing has happened. For the value that I paid the car, I don't think the quality of the PDI was up to standard or justified. Secondly, I also reported to the sales person I had the following problems, which he was supposed to arrange for them to be resolved. To date nothing has happened.<br> The included the following,The rear boiler spoiler is cracking, for a 3 month old top of the range car, one has to question the quality of the vehicle,Front passenger window does not go up fully, it forces itself in to the track.Right hand side, lip at the bottom has a gap which is very visible.Left hand side door is misaligned.There is a major rattle on the car when driving on any uneven surface .
