MRF Tyres — poor quality & mischievous act between mrf & car dealer

Address:

Chennai, Tamil Nadu, 3020

I purchased four mrf tyres 155/65r 13ttzv2k for my car zen estillo regn no. Rj-14, cj-7910 on 06/07/17 vide invoice no.016/br/17009270 from k. P. Automotives, mansarovar jaipur. Since the beginning i was not satisfied about the qulity of the tyre that i informed the service advisor of kp mr. Deepak sharma but he told don't worry in case of any problem kp will help you. On 20 the september while driving all of a sudden i found my tyre got punctured and i immediately stop the car and call one mechhanic nearby and to my surprise i found there was nothing on it and found my tyre cut from the side and that time mechanic told this happened due to problem of tyre but however he told, same can be repaired and i got the same repaired by paying rs.380 and thought i should not inform to kp and may be this happen due to my fault. But after seven days again in that same tyre i found there was less air and immediately got it checked and now i found puncture just above rim and then i again got it checked and the mechanic told in this side no puncture can happen and it happened due to defect on the tyre. Then i approach to my dealer and dealer was agreed to my logic and told same will be checked by mrf company engineer and they checked and simply mentioned this happened due to running the car after neglecting the injury of cuts in the tyre and tyres run under low inflation.
Dealer also given the same logic and they simply rejected my contention that this happened due to manufacturing defect as whole tyre was swollen all around and i think this is collusion between dealer and mrf tyre company who put one defective tyre among three tyres and thsi way they are cheating the customer. It is my view kp automotives is also involved for such type of activiites and they simply change anything even if car parts are in good condition. Their service quality is also poor.
I request the concern to kindly help me in this regard because i am not first time driving the car rather my car is 7 years old and never faced such problem in the tyre earlier.

I fail to understand how mrf company such a big company are indulged such type of activities and who instead of checking the same throughly they simply denied the same.
