ACCOUNT

I received a bill for more than R10000 for my wifi account linked to sim ***. I switched off the WIFI device in January 2015 after I received a bill of R4000 for December. Subsequent to this I paid small amounts every month for charges incurred. I want to know how it is possible to incur wifi charges to the value of more than R10000 without using the sim at all. I notice that there is usage on a daily basis still reflecting on my current account, How is that possible if I am not using this sim? Can someone please explain that to me?<br> <br> The reason why I am logging the complaint is because the Menlyn Branch of MTN logged a call/request for me on 20 April under ref ***. To date I have not received a response after I sent a reminder to the agent who logged the request i.e Gabriel Mabena but he is not responding either. In the meantime the full amount was debited to my bank account by debit order and I still don't know what I am paying for.
