Tata Docomo — harassment for non-payment of dues to non-consumer

Address:

Shimoga, Karnataka, 577201

I regularly get reminder calls and text messages from tata docomo's customer
Care team about a payment pending for the number - [protected]

It seems this number belonged to some ravichandra who earlier owned my current airtel number. But i own this alternative number since the last two
Years and i have no relation with the concerned person nor with tata docomo.

Despite my request to update their database and remove my number from it, i keep getting reminder calls from them.
