Sir, it has been 5 months since I've not been able to browse or use internet . I've register about 5 complaints since May 2020. Everytime I contact to customer care service of airtel they some date and ask me to wait for 7 days 10 days but problem is still going on. I've to attend online lectures and I've not been able to do that . In my village there isn't any service of broadband so I don't have any other options but to stick with the mobile data. I've to go out of the village just for attending lecture in open farms . It's so frustrating . Recently I've register a complaint on 6th of October and they asked me to wait for 2 days it's 10th October now but problem is still there. Apart from this my sim card suddenly stop working and I'd to pay 100₹ instead of 30₹ which is normal charge if in case of sim stops working.
Sir I hope you solve the problem and many people around here having the same problem.
And about calling it gets disconnect suddenely and sometimes the person with whom I'm talking unable to hear my voice even if he and me was in network.
