MTN Supersonic Pathetic Service

I have a MTN Supersonic FLTE package. This afternoon, the service was suddenly disconnected. On their Whatsapp support function, I received the message that my service was suspended due to non-payment. Their Accounts Department however confirmed that my account is up to date and the next payment is only due on 2 June 2020. After spending more than R100 on airtime, I finally gave up, after being cut off by their Technical support. My daughter received a similar data package from MTN Supersonic three days ago and guess what, tonight her service was disconnected with the same message on Whatsapp. Her account was suspended for non-payment (three days after receiving the package?!!!!) This is a total disgrace with non-existent customer service and clearly *********** technical staff on their support team (who incidentally call themselves "SUPER STARS")
