Inadequate account administration

The one time I managed to get hold of a customer care consultant, 🙃 I requested to change banking details. I was assured at the end of that call, that the changes would be made with immediate effect. This was in September 2022.

Two months later, I receive a threatening sms that my account is due for legal handover as a result of non-payment. I tried several times to call in, as the WhatsApp chat is useless in resolving this query, but till now, dololo.

Can we please speed up the process so that I can at least resolve this matter urgently? Maybe the legal team will be more proficient in their execution.
