Terrible treatment and zero communication

Yet again I am wronged by Vox despite being a paid-up loyal customer!

I got an email from collections stating that my account is on suspension notice, my account is overdue, and I was threatened with the suspension of my account. My bill was paid for the month of Jan/Feb 2023 and an amount of R774.56 was paid on 19 January 2023 as reflected on your records. The full month hasn't even passed but YOU say that my account is OVERDUE and you will disconnect me despite being up to date with my payments.

I sent numerous emails but I haven't gotten any response. I tried to call the accounts department several times but my airtime has been depleted because of the excessively long waiting times and the call queue constantly being added for some strange reason. All I want to know is why is my account on suspension notice when my payments are up to date and what is going on.
