Airtel — I m complaining about my slow internet speed

Address:

House no. 356 Street no. 8 radhey shyam colony phase 1 muradnagar ghaziabad, Ghaziabad, Uttar Pradesh

I m using airtel from about 6 months. In starting the speed was quite good but these days it is not working properly. In my house the networks are very low. Even social sites are not loading. I have to switch aeroplane mode many times to retain some speed but after sometime it becomes really very slow. I also face too much problems while playing online games like pubg clash of clans and any other game. I always noticed that networks becomes very very low in my house or when i open my game. I have complained to customer care executive. He shows that he is supporting me but do not take this seriously. Always tell me same tricks to improve my speed but they are not doing anything in improving themselves. I m very annoyed of them. Please help me otherwise I have to switch to another networks
