This is regarding reference no. Is[protected], registered on 30/03/2019 12:40:26. I had requested for family pack and my husband’s number to be added to family pack. Airtel immediately changed my plan from 399 plan to family plan which is 650rs, but never added my husband’s number to the family pack so that he continues to pay his bill according to 499 plan. I called airtel on 15th april and they gave me guarantee that it will be resolved by 18th april. On no update by 19th april, i called and spoke to supervisor arti rani who gave guarantee that it will be resolved within 24 hours. I again called customer care after 2 days because the issue was still not resolved, each time i had to explain the whole issue again after being on hold for 15-20 mins. This has been ongoing since a month now.
Somehow without our consent or any prior notification/update, airtel changed my husband’s plan from backend to 199 plan. He has pending 350gb of data which got wiped out and reduced to 10gb. We were never informed about this, how did airtel itself take the decision of changing the plan without the customer’s consent.
This is literally mental harassment of the customer, i have wasted endless long hours in conversations with airtel customer care without any fruit. I don’t know why i should pay this month’s bill of 650rs. I want airtel to compensate for this.
