Grand I10 Explosive Burst since 01/03/2019

Hi , my Name is Naledi Natalie Ramela. I purchased a car from Auto Pedigree on the 25/02/2019. And the car I bought had an explosive burst on the left wheel and the front part of the wheel side exploded while the car was in no motion, parking outside our parking lot on the 01/03/2019. And ever since I’ve reported this the company only came to change the wheel of the car and said they are assuming it’s the wheel cause the Manager being Mariette at the Boksburg branch has never experienced this in her 25 years of serving Auto Pedigree. It’s been three months now and the wheel is still being investigated and they have been delaying the process of this car being Replaced,Repaired or my money being Refunded by requesting quotations and affidavits knowing very well that I mentioned that In less than 5days that I have purchased a car , they expected me to drive the car to Penelbeater’s for the quotations they needed so the investigation can continue . MFC is debiting for the third month for a car I have not driven and I am still waiting till today when I ask after how long can the investigation be completed, I am told there is no time frame and that I am now to communicate with Dunlop directly and they have nothing to do with it? They have the most horrible service I have ever experienced in my life , they need to be checked out or close if customer service is not their strength.
