False Advertising and Poor service

I recently ordered the promotional R1 rain Internet modem. Rain was very effecient in handling me getting the modem to me. However, you cannot order the modem without inserting your bank details. Rain debited my account my account for R1 and the modem was delivered in the 31st October 2022. Rain then debited my account with the premium of R528 on the 1st of November 2022 and reversed the transaction on the 4th November. Rain debited my account on the 4th November 2022 again. To my understanding Rain is currently advertising aR1 promotional offer for the month of November 2022. Furtermore, I understand that if you advertise something for R1 for 30 days, you should not be debited a normal premium. I sent 5 requests for them to attend to the issue. I have approximately 10 reference numbers. A consultant contacted me last week and I could not speak at the time and asked her to call me back. To date I have not heard anything from rain and I have emails confirming that I should not be paying a full premium for the 39 days. I'm still awaiting my refund to be processed. I believe that they are either ******** clients as they are advertising falsely. When trying to contact Rain, you wait for a half of the day to speak to a consultant. I am very unhappy with the service and the poor responses.
