[Resolved]  Airtel — Slow mobile internet service

My name is Avisek Bhattacharjee. I'm from Berhampore, Murshidabad, West Bengal. I'm a regular customer of Airtel prepaid service. My contact no. Is [protected]. 27th June 2020 I recharged my sim via Airtel Payment Bank. Prepaid plan was 598 rs & After redeemed 40 Rs Coupon Code transaction amount was 558. Transaction I'd no. [protected]. From 12th Aug I faced some severe network problem. App download time was too slow, long searching times, in the time of monetary transactions faced timeout problems. I lodged complaints to Airtel Via Twitter. They only ask my area pin code but doing nothing. Still I faces network problems & they demands that their network progressing everyday. I paid full amount for 4g network, then why I'm accept this speed like 2g? Is this not cheating?
