Appalling service Dishonest

Shocking and ********* service and behavior from this Internet service provider. I went onto the Rain app and saw that I was overdue on my payment for March 2023. I took an Absa Credit card statement from the bank and it showed that rain had taken apyment for March automatically from this account . In the meantime as a loyal client I made a manual payment R529 on 03 April from My Nedbank cheque account .According to Rain this payment does not reflect by them and have asked several times for them to refund myself as this is a duplicate payment .Even called Nedbank and they confirm the payment was successful to Rain. I have called several times and last spoken to Sheenat and had to re submit all bank statements again. Rain does not provide monthly statements of payments made which is also against the CPA Act as full financial disclosure is not given Appalling servivce!!!
