Poor Service

I have seldom experienced such unhelpful assistance from anyone. I called now to enquire whether I could buy a replacement battery for my VW. I was asked for the chassis number!! Who carries this around with the!? I provided details of my vehicle. I was told that it dos not exist. Perhaps I made a mistake in one of the letters or numbers I quoted, but surely an expert on the other end could have guided me through a process of identifying my 2015 VW Amarok model. There were not many of them. The attitude of the 'assistant' on the other end was abysmal. If he was not happy to be at work, perhaps do not have him answer a call from the public.
