Airtel — retailer

Address:

Jaipur, Rajasthan, 303002

The sms received by me on 19/09/17 says to upgrade the current sim to 4g by 22/09/17. It also says that the same would be done for free. The retailer that i bought the sim from is charging me 100/- for the same. I would like to register a complaint against the retailer on account of charging me 100/- for no valid reason and taking advantage of the current situation in his own favor. The retailer has a shop in amity university rajasthan the address of which is as follows. Amity university jaipur campus
Sp-1, kant kalwar, riico industrial area,
Nh-11c, jaipur, rajasthan 303002

Kindly take some action against the retailer.
