Pathetic Service

I contacted VW Westgate this morning regarding my battery not functioning well from February. they transferred me to parts department which I spoke with one of the guys whom told me that in ordered for my battery to be checked up i need to bring proof of payment and battery when i get there they changed story and said i must book the car in why they did not advise over the phone i drove to VW for nothing when i meet them there they were not helpful the service i received it was impoverished. Very much disappoint wish the CEO of VW see this complaint. I also asked about the email i can send to complain i was advised that there is no email address.
