I am vodafone demo holder and my demo app has been misused
as my app is being used by someone else in other area and various recharges have been done from it. I was unaware of this since today

So after enquiring a lot i was shocked to know that recharge is done from my app amount cut from my balance but i didnt do the recharge.

So please help me as i dont know since when this is going on. What can i do about it ??
