New car for a month - bad service, flat battery

Got a new Tata bolt from Meadowdale branch, salesman Sydney, car was handed over with the spare key and no mats, promised to deliver soon by the manager of the branch. When we called Heino the manager, told us to bring vehicle in to get remote programmed and mats put in. Car sat at the dealer for 4 days and when collected, nothing had been done and the car battery was flat. We had to jump start a new car. Called head office customer care, and still waiting till today. No one is managing the customers at Tata correctly. No one is giving us the correct information or guiding us in where to go to rectify the problem. And the manager from Meadowdale doesn't even follow up with the situation. I've received some bad service before, but this definitely breaks the record on shocking service delivery.
