MTN bulling tactics

I am being billed for an iPhone + contract that I did not authorize the purchase of and which I did not receive. Opened a case of ***** with SAPS CASE # 103/12/2022 MTN are reluctant to attend to my e-mails as well as my numerous phone calls. I have stopped the debit order for my 2 other phone contracts that I have with MTN.. MTN demand that I keep on paying for the "*******" phone and sent me a sms that if I don't pay they will cut off my service despite the fact that the money they have *****fully deducted via debit order is greater than my monthly account for my other 2 phones. This is a situation of pay up till we decide to attend to the problem. I wonder if the MTN individual or agent who authorized this ********** transaction will suffer any consequences
