Airtel — about negligence of customer service on airtel

Address:

Aizawl, Mizoram, 796001

I send a complain in email on [protected]@airtel com about my data plan which is expired on 30 september. But i recharged with rs. 499 which got an offer for 105gb for 84 days on 2nd september. Due to negligence of customer service by the name lakshmikanth ambekar who don't give any reply for further information. Would you please kindly solve my problem? Plus i have a 4g sim and 4g handset which is compatible on the offer made. If you can't extend my data plan i kindly request you to send me back the money for which i recharge for. And plus one thing i can't get amy call or make a call while i'm using in 4g network. Please if you could resolve my problem, i'll be very thankful to you
