Airtel — No customer support, cheating

Address:

Anakapalli, Visakhapatnam Dist

I am using Airtel mobile services from last 10 years. Of late I have recharged with Rs 251 twice to utilize 50 GB 4G data. Airtel collected the money but while using they are not providing 4g speed. There no customer support as well to talk or complaint against it. When ever I am trying to report it through their bot in Airtel thanks app it is showing that I do not have enough data balance.

They are alluring with different top ups but not providing the customer support at all.
