Tata SA, worst servie ever

Ibaught a new Tata Bolt xt 3 years ago. In the 3 years i has been back to the service center in pinetown 3 times because it keeps blowing the exhaust gasket. I took the car in in November 2019 for the same problem again, they told me they need to replace the head. I was also told it was a problem with this model. It is now February and still no car and noidea when i will get it back. Was told by Jan Maritz at head office that he would keep me informed, havent heard a word. So my advice is dont buy a Bolt because they are problematic and there is non existent service delivery from Tata sa.
