Billed for Services that don't work

Mtn has debited close to R500.00 from my account for what I really don't know , considering I have been unable to use the sim card hence the phone since I received it , I have not received a statement or invoice for this debit ,so what exactly are you debiting my account for? A phone and sim card that I have and cannot use because MTN has not provisioned the sim and deemed it usable for me???<br> I can't understand how MTN can debit my account when the sim they have provided me is not provisioned hence services on the contract cannot be utilised?? Its almost 2 months and the sim has still not been sorted by MTN, the onus is upon MTN to get the sim provisioned as the sim card was provided by MTN,I don't have the time to run behind to get a simple thing as a sim card activated and provisioned...I have a job , my job is not to run MTN behind for services they provide,MTN , I expect my funds to be returned and the sim card to be provisioned and usable on this phone as soon as possible , not 2 months possible but this week possible i.e. by close of business 03/03/2016.This message has already been sent to [Email Removed] and they say they cannot find the \number\" on their network or system."
