Can't Get Hold Of Any For A Specific Billing Charge

Customer Service, I cannot contact anyone to assist with a query as I have been billed for something that I don't know what it is. I have tried calling, I get through to Tobi, who can only answer certain questions. I use online chat and the same. I need to know why i have been charged for: Direct Provisioning All for You Bundle 1GB + 100Min Total Direct Provisioning And I cannot get an answer for this or a contact number to call that doesn't put me through to an automated answering machine.
