Date of incident: from august 2017 to till date
Company - airtel
Incident - internet connectivity issue and signal drops (Postpaid)
Description - i am continuously following up with the airtel customer care through calls and mails regarding the internet connectivity issue nd sigal drops in my locality (Ashwath nagar, marathahalli, bangalore). From last 1 year, the issue is not fixed yet. I questioned airtel about the issue and charging for not been used or access internet.
Airtel has been telling as india's fastest network in india. But it doest qualify to say that. I have proofs to justify this.
I have tested jio and airtel speed test at same time. Airtel shows about 460 kbps speed whereas jio shows atleast descent speed of 2.6 mbps at the same place and same time.
I wanted to register a complaint on airtel for saying airtel as indias fastest network and fooling customers to grow there business. Please help me on the same.
