Still debiting for cancelled contracts

After I cancelled various VA products with Elite mobile I noticed now in 2016 that they have been billing me for those cancelled products continually since April 2015. Because it's small amounts here and there I just didn't notice. When I called the call agent just said that I should contact those suppliers directly. Who are they even? <br> My contract is with you and you are the people deducting the money from me. Please refund all my money.<br> EM ***-3<br> EM ***-1<br> EM ***-6<br> EM ***-7<br> I'm sure all those recorded conversations will serve of evidence that these are unauthorised debits.
