Rain Cut paid service

I'm struggling to get my internet restored with Rain, what happened was on the 20th of March on the RainGo app I made a promise to pay which I made a R50 payment and on the 1st of April I made the remaining payment of R519 which come to a total of R569 then on by the 3rd they cut the service, I contacted them and asked what's going on they said I didn't make payment so I said I made the promise to pay through the RainGo app through card payment, so the lady said send the email with the screenshots of payments attached and the billing department will correct it the following day it's so cut off and I contacted 4 tube that day sending emails with the screenshots of payments and the 4th gentleman I spoke too said that he will send a follow Up to the billing department with the attachments and Reference: ***0 , since then I'm sitting without a service that I have paid for and I'm not getting any help from Rain
