VW and dishonesty

I don't have a disliking to VW, but my advice is stay away from VW Polkwane. My son bought a polo tsi about 2 months ago and the vehicle went into limp mode, it was taken in to Lydenburg at which we were told it needed an upgrade - what brand new car needs an upgrade. After a huge amount of threats the Polokwane dealer phone and said he had found a replacement vehicle. My son went to collect the new vehicle only to find that it was not new at all of which I have photos as evidence, is it not bad enough that we need to deal with corruption in this country, now we have a supposedly reputable company doing this to a person. They should remove their adds on tv, as they definitely don't stand by you, but rather fu.... you. I will not rest until this has been brought to light.
