Address: 841417

3g services of my area has been stopped from 15days. My address is jajauli, po-bansohi, mashrakh, saran, 841417. I have called many times to the customer care no 198.But they use to tell that 4g service is being upgraded in you locality that's why your 3g service has been stopped. But this is not the problem of this month only, from January 2017 each and every month this problem arises and whenever we call to 198, they use to say that 4g services is being upgraded. We recharge for whole month, but we are able to use the internet only 10 to 15 days.
