Shocking and Unhelpful Customer Service!!!!

<p> I dropped my car off for a service on Tuesday 6th August. The car was in fully working order and the service was carried out. When I sent someone to collect the car the battery was completely flat and the car had to be jump started. When I eventually went to fetch my car from a nearby garage where it was parked the car refused to start as the battery was completely dead. I call the service agent the next day and they initially said there was nothing they can do. They did eventually fetch the car from the garage, which again had to be a jump started. I was then called by the service agent and told that they had not tested the batter as it was an "aftermarket battery" which makes absolutely no sense, but I was not informed that the battery was not tested in the first place. I was told they will replace my battery for R3000+! Besides the fact that I am not willing to pay that ridiculous price and negated to tell me the battery was not tested, I will NEVER be using Barons PMB again for any of my dealings, as when I dropped my car off it has been starting perfectly fine and all of a sudden the battery is completely dead. I even queried if the lights or any other electronics would have been left on during the service, because I cannot simply not understand how a battery can simply die during the course of a day! I would never suggest anyone use Barons PMB after this experience.</p>
