Additional payments requested after paying 7 days ago!

I paid R400 on the 30th December, today (06/01/2020), I received an sms advising that my services will be disconnected, and that I need to pay R191.24. Can I just confirm that it's R208.76 for two days of DSTV? I need to understand how my payment was allocated, even if I had a reconnection penalty fee, how is it possible that i need to pay an additional (almost R200) 7 days after making payment? When the payment I made was for reconnection in January. Another issue I have, is that I cannot login to my app, always getting an error and an email address to use as a point of contact, but the email address is unknown and also returns a failure?
