Airtel — 2g speed on 4g network

Address:

Nainital, Uttarakhand, 263139

Being a loyal airtel costumer for over 8 years i never had much problem, recently after jio, the internet speed have been worsen. From downloading a 1gig file in almost no time, now it takes more than a day for half gig. The seed promised are to be 4g but the speed i'm getting are 2g rebranded into 4g. It's been over a month now and no response from airtel. Thinking to port over jio now. Totally annoyed by the service provided
