Wrong invoicing, indiscriminate debit order!

MTN is a company with a problematic invoicing system. This is not the first time I've received odd bills and had funds debited from my account. The same thing occurred in 2016, and rectifying the error took time. I revised my plans following the expiration of my first contract on 27 November 2021. My new plan is less expensive than my prior one. Nonetheless, they have removed the following funds from my account:

I had changed my 31 Dec MTN SP BA***00002 debit transfer - R3 432.27

30 Nov MTN SP BA***00002 debit transfer - R2 339.25

Both contracts I now have with them need a monthly payment of less than R1000. I am purposefully publishing this here to bring attention to this wide daylight institutional theft!
