Rain extremely bad customer service

All I wanted to do is go from a unlimited off -peak to pay as you use however Rain decided to deduct R250 in May & June when I used absolutely no data at all! When the lockdown started, I worked remotely & have fibre at home therefore I did not require to use my rain data. When I went to the dashboard, there was no option to downgrade to pay as your earn. I sent a ticket *** on 01 May to advise them that I want to downgrade. I took screenshots of everything to show them that there was no option to downgrade my option. I struggled to get this sorted for 30 days so I decided to cancel my rain sim card on 30 May. Rain then deducted another R250 on 01 June. I then submitted another ticket *** on 01 Jun & followed up every week however nobody has bothered to provide me any feedback & my request for a refund. Even though I was generally OK with their connectivity, Rain customer service is the worst I have ever experienced.
