MTNL Mumbai — High bill

Address:

Mumbai City, Maharashtra, 400072

Dear sir / Madam,

I am getting very heavy bills. During last year, it was 7, 000 Rs. it was too much

Now again, it has started increasing. from avg 342 it went to 1000 Rs. I am not sure what is happening.

please help in getting the issue resolved as it is very disturbing financially to pay heavy bills for no use of phone.
