Why am I being charged cancellation fees???

I have two account at Cell C, lets name them 084 & 074.<br> <br> 14 December 2015 a settlement amount to cancel the 074 numb. was paid in full (including the current month installment)<br> 1. Phoning cancellation department to obtain settlement amount and inform them of intention of cancellation<br> 2. Referencing the payment as the 074 number<br> 3. Phoning Billing and Cancellation to instruct the moneys to be allocated to the 074 number<br> 4. Fax instruction to Billing & Cancellation that 074 was paid in full and should be cancelled. <br> <br> End December, 084 was not debited, 074 was not closed and at end January I'm sitting with a R1060 bill for Cancellation fees for the 074 number and the 084 number that was not debited. <br> <br> Billing department was absolutely useless and could not help once, in the total of more than 4-hours I was on the line, cancellation just blames Billing for the mistake. No one is of any help! <br> \Team Leader"knows just as much as the call center employees"
