Tata Docomo — balance deduction

Address:

Thane, Maharashtra, 421301

I recharged my phone on 22nd february 2018 for a talk time of rupees 160. When i checked a few days back, the balance was 0. I have not made any outgoing calls from this number neither have i used the mobile data since i have wifi at home. I can't make any calls to the customer care since i don't have any balance left.

My phone no is [protected]
