Terrible service

I bought a new Tata Bolt two years ago, which is my second Tata now. The service when buying the car was terrible, i was told that i could pick up the car in the morning only to wait the whole day to receive my new vehicle. First service great. Second service took the whole day and on my way home which is 250 km away the car gives problems. After a lot of fighting they send a mechanic to repair only to find out they damaged HT lead when servasing. Then a week later the car blows a exhaust gasket, workshop says stud broke. It took 3 days to fix. I had to arrange a way to get back home and then drive back when the car was ready and return home with two cars because they don't have a courtesy car for me. Now about a month down the line the car has the same problem they say i will have to bring the car in then they can do a warranty claim and then repair. This means i have no car for at least 3 days again . So i have to travel down with two vehicles again and back again. i warn people to be careful of buying here bad service , no courtesy vehicle and bad workmanship.
