Airtel — Not resolving the complaint from 3 years

Address: Hyderabad

Hi Team,

I have given a network complaint around 3 year back, without notice Airtel team is resolved the ticket and in Complaint history also they removed everything, this is not a one time everytime, about 1.5 year back also given and its closed without notice and 1 month back also called for complaint and raised and asked the previous complaint but they said as last time, there is no complaint on your number, this is the first time, and I am paying Bill on time but service is not, I am totally frustrated, I have email proof and call Recording proof with me.

Please check and do the needful for the same.
