Incorrectly Billed!!!!

I received a bill from Telkom charging me for a router and 10gb of data. I have called in 5 times this morning and kept getting told to contact various departments, which I have done, yet my issue has not been resolved! When asked how this service has been activated as I didn't receive a router, no one can answer me! I am just told that everything is correct on their side and according the their system, I should be billed. Please send me the paper work showing that the item was delivered. And send me the recording where I ordered this product!!! I am tired of contacting your call centre and being sent from pillar to post to resolve an issue which was created by your staff!!!
