Billing Errors

The following query references *** & ***) was closed without notifying me and according to the customer service agent, these are not sorted as yet. An amount of R314.82 ex VAT was charged to my account for a handset fee for one day. This is incorrect as the monthly handset fee is R350.00 Incl VAT. (Pay back the money) Then I also logged a query asking why my free minutes, sms's and data was taken away when I did an upgrade, after I have paid for these services. I want those to be refunded to my account as well. If I dont get this sorted within this week, I will take further action as I am getting no joy from Cell C customer service.
