WORST TATA BATTERY

Servicing and maintenance was good upto 3rd service. I have driven my car to 7800km in 18 months and now problems after problems coming out the small interior materials used inside the front banet is sub standard one . Tata battery is again the worst one I have ever seen. Battery had a warranty of 18 months and on completion of 18 months and 15 days the battery is dead and i have purchased a new battery with 4 and a half years warranty. And much more i can tell.....
