Services disconnected after payment was made

I made a payment on my account on 30.1.20 after being notified on the same day via sms and decoder mail to "make a payment of R200 to avoid a reconnection fee". My service was active at the time so I made the payment via left as I normally do. This morning j received another sms and decoder message telling my service was suspended and that I needed to pay R250. I then called the call centre and I was informed to email my proof of payment. After sending the email, my service was not reconnected so j called again and I was informed that I had to submit a pdf doc as proof of payment. The aging then informed me of a shortfall of R50 to which I responded that the sms and decoder notification said R200 yesterday and I promptly paid. She enquired whether my service was active st the time of payment and i confirmed that it was active. She then said the R200 proof would be sufficient as I paid before being disconnected. After sending the email with the pdf proof I called again but this time spoke to a different agent who had me on the line for 40mins without being able to resolve my query. I then spoke to another agent, thinking she was a supervisor but after 23mins she opted to drop my call after telling me she would get me a supervisor.

The same message I have been getting from these agents is that I cannot be reconnected unless I pay R50. My problem with that is, at the time I made a payment, my service was active. I was disconnected the next day after. Why should I pay for a reconnection fee when I was disconnected after making payment?
