Debiting my bank account

There were deductions made on my bank account. I haven't received ANY product from Elite Mobile but deductions been going off from 31 December 2014. When I queried about it, the operator said that they will investigate and come back to me. Firstly, I don't have any account with Elite Mobile and secondly I didn't give them any permission to deduct anything from my bank account. The numbers concern is .... EM ***-1 to 6. Please investigate urgent.
