Poor tyre performance

This is in continuation with my previous rating. Ecosport titanium tdci purchased on 12 jan 2018. After approx 2900 km, rear left side MRF tyre got burst, contacted dealer, they sent the tyre to MRF for inspection, MRF said , it's not a manufacturing fault. Despite of my all pleas, I had to change that tyre by paying 50%amount from market. Now, yesterday, the 25th Jan 2019, total running of car approx, 8800km only, again the rear left side new tyre got punctured, You will say, this is normal thing. Yes, it is, but the tyre eco sport is otherwise a very good car
