I recharged my MTS Mblaze prepaid 8646899591 with Rs 1999 on 8th Feb. an offer was showing up from MTS saying i would get 17 gb instead of 15 gb with validity for 90 days if i recharge with Rs 1999 within 10 February. but till now i didn't get the extra 2 gb. i repeatedly emailed MTS customer care but till now they have done nothing. and also sometimes MTS is not giving that internet speed which they mentioned. i need your help. please do something.
