Tata Docomo — deactivating my sim without prior information and trai guideline says I will be getting 15 days grace period

Address:

Aligarh, Uttar Pradesh, 202001

Hello,
I had been using TATA DOCOMO services since 2009. Lately, I have been away from India (in Canada) since July 25, 2018. As a matter of fact, I use a Canadian local number here. I use my TATA DOCOMO Indian number in my phone to receive OTPs for banking and other important services.

Recently I came to know that my number ([protected]) has been deactivated since January 16, 2019. As per TRAI regulations, I am liable to get a grace period of 15 days( see point V in document attached- TRAI guidelines) to recharge my number to retain its validity. I tried to do so on January 29 but failed, denoting the number to be invalid. I immediately (January 30) contacted their customer support who said that the number has been disconnected and it's not possible to reactivate it again (Please see trailing mail from TATA DOCOMO customer service). As I was within the 15 days grace period, it's ridiculous how the service provider made such an action. In addition to that TATA DOCOMO service provider support was negligent even to address my issue properly and kept on telling that the number was not possible to reactivate again.

Needless to say, how important the number was for me- especially linked with my Aadhar, three Bank accounts, PAN and other Government sources, I am in great trouble. I have my hands tied also, being outside India presently. I would request you to look after the matter in all concerns and revert back to me with a solution. Please do not hesitate to ask for any further requirements.
