Dissatisfied with Rain

I have a complain to raise regarding Rain, I paid my account via their Rain App R569.00 on the 25th of February even now my Rain has been disconnected because they are saying there's no payment received on their side.. I have called Rain multiple times with no assistance they are telling that they have escalated my issue to their billing department. I've been also chatting to their online bot and sending through proof of payments. I'm so disappointed and dissatisfied with Rain at this point. And another thing I don't understand is how they are saying on my account that I'm in arrears for 2 months meaning February and March I owe them 🙃 how is that even possible. I called Capitec also to check if the issue is not on their side but it's not ...I have proof of payment. Even on.my banck statement it shows I have paid on the 25th of February immediate payment. Please help
