I purchased my vehicle from Clovis VW in January 2...

I purchased my vehicle from Clovis VW in January 2016. I recently took it in because the AC was not working properly. It ended up being covered under warranty and they fixed it. However, they called and told me something was wrong with my aftermarket battery and that the car was having difficulty starting. I explained that I purchased the vehicle from them brand new and the only battery that better be in my car is the one it came with. They said they would call me back to clarify. On the 2nd phone call they said oh the aftermarket battery belonged to a different car but your battery is bad also. Up to this point I had never had any troubles with my car starting or the battery. The service tech went on to tell them that after doing some research that he noticed I did not purchase the vehicle from them. At this point I said I did purchase it from them and the sales contract was still in the vehicle to get it out and look at it. He continued to say I did not buy it there. I told him do not touch my battery and that I would be there to get the car. About an hour later I called for the shuttle service to pick me up, The same service tech answered and at this time told me he was charging my battery after I told him to not touch it. I got to the dealership and now all of a sudden he has a picture of the battery in my car. My question is did he take this picture before the battery was taken out and before he called to tell me the wrong battery was in my car or after they realized they switched batteries. I also wanted to know if they put the wrong battery back in my car originally. The one they said was mine (aftermarket) which was not. He also went on to tell me about how my car was transferred in to the dealership which it was not. I went to the sales manager and had clarify that I purchased my car from them directly. Now all of a sudden my battery is dead 2 days later. I find this to be very suspicious especially since I never had trouble before. I am extremely disappointed in the service I received. I had been in before and had great experiences so I never would have thought I would have to write this. Their remedy before I left was that they could sell me a battery at their cost but I would still need to pay the labor fee of approx. $73.00. This was not acceptable to me considering that I had not had troubles with my battery up to this point and they they did not know which battery was mine or if they put someone else's in my car or not.
