I am complaining about the isd call made through my number ([protected]) without my knowledge when i had never opted for isd facility for my number. I have no history of any isd calls what so ever till now right from day 1. I received a bill and a message stating that my limit has crossed 3000. I was shocked to see that sms. I want clarification on the following;
1. How can vodafone enable isd facility without my concurrence or request.
2. I have no history of isd calls till now.
3. I had never requested for isd facility.
4. I had never accepted any such request for isd facility from customer care.
5. I had made a complaint to the customer care multiple times but they said the call has been made from our number but no one replies to the question how isd facility has been enabled when i had never opted for it.
6. I fear that the call which went through does not belong to me and if in case of any issue in the future i may be held accountable for it. I had made complaint of the same to vodafone customer care but did not get any sensible or responsible reply for it.
7. Now my number has been disconnected of service due to non payment of the bill.
My question is why should i pay the bill when i have not made the call and the background reason being that isd facility was enabled without our concurrence is still a mystery and unanswered.
Please take it on priority because i am very much affected due to the disconnection of my mobile service. Vodafone will only have to take the responsibility of all teh above and give a solution for it immediately.
