Mahanagar Telephone Nigam [MTNL] — Security Deposit Money haven't received till date

Dear Sir/Madam

I Hiten Savla have cancelled MTNL Landline connection on 31st Dec 2021 but haven't received the security deposit of Rs 5000 or so till date. I was been told that i will get refund in 90 days but haven't got yet. So, request you to refund my security deposit. My Telephone No. is 4127888 and I have cleared all due payments while submitting the cancellation request on 31st Dec 2021.

Thanks & Regards
Hiten
