Poor service!!!!

Never ever have we received such poor service from a dealership after buying a car. We had problems with the battery being drained every day and needed to be jumpstarted daily. After numerous attempts to contact the manager we never got feedback. There were no communication at all and his excuse was that it's not his department and that he was busy. So we had to sort out the problem ourselves. Eventually we took the car back as we took the car to an auto electrician and they concluded that the fuse box underneath the dash needs to be replaced. It doesn't switch off at all. That's after we had all tracking units removed from the car in order to see if that could be the problem. We had no assistance in this matter. We weren't contacted. They didnt reply on our mails or messages. I have been without my car for a week already and now its back at the dealership for another few days. So disappointed in their service!! And still no apology from the manager!!
