4th HP complaint for the same issue, as CellC can't resolve their issues!!!

Reminder, thnis is now the 4th complaint about the same unresolved issue: I cancelled your fixed LTE-A contract 16th Nov with immediate effect - Due to erratic and consistant network issues in my area. check all my calls logged ( ********** 673). As I have cancelled another contract month earlier I knew there would be a final payment, so I left my stop order to pay it on the 23/11. THEN YOU GO DEBIT MY ACCOUNT without my permission, as I have always paid CellC through EFT cause you keep messing up my account. Thabisile Ncogobo, first couldn't find the payment stated above, then all of a suddent she did. Since then I have been promised payment and it did not happen. On the 11th I was sent so-called proof that payment was made, and promised that it would relfect in my account the following Tuesday, buy the next Tuesday (18th) still NO payment reflected in my account. After numerous follow ups I was requested for a bank statement to confirm I was lying about not receiving the payment, I sent through a screenshot of all incoming payments into my account since the 10th, as I was not going to get charged by my bank for a statement, for your incompetance! Last week Thursday after more follow ups, I spoke to ********** at your Midrand HQ and AGAIN asked for bank statement. ***? I showed my banking app incoming payments and confirmed NO payment received. I was told by her manager that they would check with Finance dept. (AGAIN?) I was also told that I would be eother called back or emailed the same day with feedback, its again the follow Monday and still no feedback and I have followed up. I have no been more than patient, if no refund is done, I will pay January short by R688.88 and take this to the complaints comission, as I have already complained to ICASA
