Tata motors bad service

Tata Bolt XT beautiful car great features but terrible after sales service. I have a 2 year old bolt 35000 KM on clock. keep having a problem with the exhaust gasket blowing. complained to Tata motors SA just don't get any joy out of them. they have a joint franchise in Pinetown KZN where i bought the car. The service is just as terrible. Takes 3 days to replace a gasket they don't have a courtesy car either. Wow ! So my advice to people out there be careful yes the cars are cheaper and not bad looking but you wont get after sales service and they seem to be problematic.
