Exide Industries — malfunction of the battery and rude and arrogant behaviour of the dealer

Sir,
I purchased a car battery no. Mred-35 r a 4 f 7 e[protected]f31 on dated[protected] from your dealer maa gayatri battery service, aliganj, lucknow through my mechanic mustkeem service centre. It was not working properly, so i submitted to this very dealer on 18-6-18 and got it back after few days with assurance that now it will work properly.
It malfunctioned again and was submitted to your dealer on 14-8-19. I contacted this dealer of yours on 16-8-19 on his mobile no. [protected] and was shocked to receive rude and arrogant reply that he will talk only to mr. Mustkeem and i can do whatever i wish, even make complaints to the company, such reply and behavior is not expected from a world reknowned company representative.
I demand for a strong action against this dealer and request you to change/ replace my car battery.
Thanking you
Yours sincerely
