Bad service

I had a problem with my car. It doesn't wanna start. I took it to battery centre since the tracking company said it's the battery. So I took it to Battery Centre and they tested and said - my battery is fine, it just needs to be recharged. Ok cool and I booked with VW autohaus since it's still under warranty and on the 22nd of May 2018 I took in for a service and everything they said was fine but after 3 weeks I started experiencing this issue. On the 10th of July 2018 I took it in and they said they will do tests and if they find that it needs to be recharged they will recharge overnight ok cool - and I asked if they can drop me off at my place since there's no transport to where I stay they said they can't and and and ok cool... I was advised that if there's still issues still today they will replace the battery and around 12 I was told that I might be asked to pay and it's expensive. Ok cool I call again around 3PM since no one bothered to update me of the outcome and I was put on hold however the lady said they will call me and let me know of the outcome.... I am not gonna pay anything since it is still under warranty. and they should have said yesterday. At 5PM I emailed the lady since she never called or anything to let me know if I won’t get the car still today as promised and she said I won’t get the car today and I must deal with that, because she’s trying on her side to and she said was she’s still waiting for the warranty officer to decide whether they are going to put it under warranty or not.

I have never changed or added anything to the car ever since I received it except for a tracking device. If there was something faulty they would have said when I took for a service and after some tests yesterday they saw that the battery needs to be recharged or replaced that's it... Now they are coming with stories and here I am struggling to get home and to work. I have spent R500 for these 2 days on Uber and I cannot be spending more and still be paying for this car.

The attitude I got from the lady and the service I received is disappointing.
