I am facing billing related issue.
Airtel had unknowingly changed Landline/Broadband plan for me and not even sent printed/soft copy of the statement/Bills. I had paid excess amount for 4 months of changed plan by Airtel. On 5th Month when contacted Airtel Bangalore @ 121, they said they will do full wavier. I spoke with 20 executives of Airtel and tonnes of email since 4 months, but, no reply from Airtel. Landline/Broadband is inactive since 2 months and causing lot of inconvenience. Airtel need to pay me back the excess I paid, but instead Airtel is asking me to pay the bills for the months I have not used. There is no itemised billing in any of the recent bill sent since 2 months. Airtel had become purely Customer Cheating company and causing lot of incovenience to Customer. And on top of it, Bill recovery team is giving Threatening calls now and then.

landline : 080-42070549

Details:-
I opted initially Rs. 799/month.
After shifting house to new location, Airtel had changed plan to Rs. 1499 + Tax, which I dint asked to change and not signed any document and neither sent any emails to Airtel for change of Plan. Airtel had not sent Bill statements for starting 4-to-5 months from change of plan they made. After I insisted strongly to send bill, then finally managed to send bill after 20-30 days of next subsequent month's.
Plus waiver/refund of charges phone shifting charges which Airtel had agreed much before, shifting of landline to new house.

I am planning to complain to Consumer Court or TRAI.
