Tata Docomo — barring out going calls of active prepaid sim with balance quoting expired sim validity.

Address:

Mumbai City, Maharashtra, 400081

Tata docomo barred my out going calls quoting expiry of prepaid sim card.. As per appellate authority every month minimum recharge is essential to keep sim valid.. Just wanted to kno
1. How can anyone force me to recharge with any amount when my number is active???
2. My sim validity when i ported my number had a lifetime validity how can they change it without any intimation???
3. Why was only out going calls stopped if my sim validity is expired despite having balance and blocked to use my balance?? If my sim validity is expired then entire number both out going and incoming should have stopped.. How can they block only out going on prepaid sim???
