Airtel — deficiency in their services and unable to resolve

Address: Mumbai City, Maharashtra, 400003

I have been using aitel number since last 2 months. My plan is of rs. 399 on which i was told that i will be given unlimited calls and 100 sms's per day and 20 gb of 4g data. I was mostly attracted towards 20gb of 4g data because of which i chose to be in airtel but however while using the service of airtel 4g i am very much shocked and surprise to see that the speed of airtel 4g was not even the speed of 3g. I mean i am not getting enough speed to that i can consume, utilize the 20gb data of internet 4g which they promised. I am not able to watch any movies i am unable to see any videos without waiting time (Buffering) videos, movies are lagging so much that i am unable to use the dedicated data provided by airtel. I have made several complains to airtle regarding the same issues they says that their network is on upgradation. I want to know why shall a consumer should suffer for your technical problems. But however they couldn't resolve the problem nor were able to provide my the with discounts. I mean why shall i pay the complete bill amount if i am unable to use the services.
