Very Poor Kia customer service

My Kia Sportage AWD was damaged by a truck when the truck's brakes failed and it smashed into my parked Kia, the accident took place on the 16th June and as it's under warranty, it was taken to the Kia approved panel beaters. However there are no spare parts so they have to be ordered. The order will only arrive in August!!! So that's 6 weeks before my car even get's looked at. So I called Kia Diep River to see if they could help me out for a portion of that time with a courtesy car seeing as it wasn't my fault that there's no spare parts, but they could not get rid of me fast enough!!! So much for customer loyalty, as a family we've spent over R 750 000 with Kia buying two brand new Sportages over the last 5 years, funnily enough nothing was mentioned then about the lack of spare parts!! So very disappointing customer care from them beware!
