Charging me for something i never subscribed to

I have a contract with vodacom<br> R399 Phone<br> R10 i think for caller indentity <br> R 9 for the sim i think.<br> <br> So im used to pying R419.00 now i have been paying for R40 extra at times and would still have data, minutes and sms remaining. I contacted the chat session online and they said i subscribed or clicked on some icon on my phone and cant be deactivated. I then asked one lady to tell me coz when i click on it with her on the phoen it didnt wanna go through. so how would i have subscribed to it if i cant go on the site. <br> <br> I need my money to be reimbursed. Im due for an upgrade and dont think il do it bcos you rob ppl of their money. no one even explains in simple terns wat that is.
