Airtel — not able to connect to customer executive

Address: 272201

Dear sir,
I purchased an airtel 4 g sim (Mobile no. [protected]) on 09th jan 2018. Since that time neither internet is working nor call works smoothly and also i am not able to send sms. Regarding this when i tried a number of times to connect to customer care executive but again i am not able to connect to them.
They claim to be the fastest network. But they are cheating and looting using that name and banner. They cheat.
Due to this i have suffered a lot such as banking/ personal/ official and others.
They do not care about customers.
Please help me and ask the company to compensate my sufferings.
Please do the needful.
Thanks in anticipation.
Yours faithfully,

Manoj kumar
