Bharat Sanchar Nigam [BSNL] — there is a problem with internet access in my bsnl card.

Respected sir/madam,

I have been having this issue since last week. I have my internet balance done in my bsnl card yet i am not able to receive any kind of internet access. I am fed up of this. I have been trying to connect with the servicemen but the issue is not yet resolved. I am a final year student. I need to finish off my assignment and projects. I need the internet. I pay rs.333 for 4g 3gb internet with validity of 58 days and most of the time the internet access is not present. I will be very grateful to you for resolving this issue as soon as possible.
Thanking you.
Yours sincerely,
Mohit m. Gupta.
