Airtel — net problem issue

Address:

Hisar, Haryana, 125001

Dear sir/madam,

I want to tell you that i'm a customer in airtel prepaid number last three to four year's. I have many times contact your tollfree number or your airtel office in model town hisar. But there is no response due to net problem.

I've also use airtel prepaid number in my home many number's but enough. I've changed my all number in airtel to another prepaid number.
In last four to five month's i've not using my 4g net properly. There is a very poor network or service problem in last 4 to 5 month.
