Rain Rain go away......Poor billing service

So I recieved my Rain One Modem, and Sim Cards activated on the 08th August 2023. I setup my debit order date for the 15th of every month, having noticed that my first debit would be on the 15th of September as per the My Rain App where I can view my account. On the 15th August I got debited, but did not have funds in that account as I did not budget for the debit this month. Account was then suspended, could not change debit date on the app so sent an email to the help desk requesting payment date be changed to september and please reactivate my account. 2 days later account reactivated and payment date changed to 1st of September, cool sorted so I assumed. Today another debited tried going off and account suspended once more. Payment date is still the 15th for this month but then payment due the 1st of September again. so Rain basically want me to pay 2 installments and I haven't even had the device for 1 month already. So much for use now and pay later. Since I've had this device, its been more suspended than active. Rather just cancel and go back to Telkom. my reference number is ***. I'd expect this back online as soon as possible, payment date set for the 1st of September and the arrears amount removed.
