Worst service in history of WiFi

I am so disgusted in rain 5g !!!!!!!! I've been struggling with my billing dates from the month of August. And yet they are still debiting me the 15th of each month when agreeing telephonically my payment date is the 1st of eachother month . I've sent multiple emails to the rain support systems as received telephonically as well and they now expect me to pay twice in one month. I called the customer service department yesterday (16.12.2023) to query as to why my internet was cut, I spoke to Sanjay who advised my account is in arrears for October and there is an outstanding balance of R1040.94 I then advised that amount was paid on the 30th of November leaving my account in a 0 balance Sanjay sounded very confused and then told me my account is in arrears from August and dropped the line which is very pathetic service!!! I called back to speak to someone in the complaints department which I came through to Ayanda, she advised my account is in arrears from October which i then explained again that the full amount was paid on the 30 November, i asked Ayanda why my service was cut when i requested my debit order to go off the 1st of every month, i asked to speak to a supervisor and then Ayanda muted my call, I can't believe this horrible service of Rain and the *********** staff!!!! If this is not sorted I will have to cancel my account and take you guys to court!!!!!!
