Locked account????????

I opened a contract with MTN last year October at campus square since then only 2 debit orders went off and nothing since... I did a manual payment for the missed debits Jan and feb at greenstone and asked the consultant lebogang nkwe who processed the payment to change my payment option to manual as the missed debits would result to me being handed over to the legal department. Viewed my statement at the end of April with an outstanding balance of 900+ meaning the payment I did in March was not processed I then paid an additional 600+ for the months of March and April Via EFT due to “lockdown” today went into the store where I opened my contract I was told that my account has been blocked and handed over to there legal department was told there’s nothing they can do for me I must call the customer service iv since been holding to be put through and it’s been 15 min and still no consultant to talk to.
