Poor service from 30/10/21 to 01/02/22 query not resolved yet.

Yesterday 31/01/22 I saw Octavia at MTN Direct in Nelspruit to try and solve my problem with MTN. Paper trail also given to her. Today 01/02/2022 MTN try to debit my account with R2100 but I immediately reversed it because my query was not solved from 30/10/2021 until today although I spoke to consultant at customer care (ref no*** and numerous e-mails to Mondo Customer care. MTN want money from me but they can't solve my problem and suspended my phone. I am prepared to stand in court to defend myself if required to do so.
