VW - shocking customer care!!

I am absolutely shocked by the after service at VW South Africa. I bought a brand new Polo GTI 2 months. I hit a pot hole a week ago and was then told that I need to buy 2 tyres as opposed to 1 as VW hadn't brought in any more of that brand. Lindsay Saker then advised that VW will give me 3 tyres for free (in a different brand) and i can pay for 1, which i was happy with. 7 days later and i cannot get any feedback. I then get to deal with Earl in customer service at VW.. Probably the rudest and most unhelpful human being I have encountered and he is in CUSTOMER CARE ?? He then informs me I will have to wait for another 5 days to get my tyres, so that VW can negotiate pricing !! Are you kidding me??? My car must sit in the garage (unable to drive) for 2 weeks so that VW can haggle for pricing on tyres, after i paid 500k for a car !! I am disgusted. I will NEVER buy another VW in my life !!
