Rain is the worst service provider, it's all a ****

I have having a terrible experience with rain and it is turning out to be a nightmare. They have been deducting from my account for a Sim card that has not been active for over a year. I spoke to an agent in January to cancel that Sim card and he promised they would not deduct in Feb. They still did. In April they closed my internet access on the 3rd. On the 28th. I called in and explained my situation. I spoke to quinton who assured me he would log a credit for the months where they deducted for the old Sim and he told me if I needed my new som active, I would have to pay R 292. Which I did. He assured me they would not try to deduct again. Saturday, Sunday and today. They have been trying to deduct. And they have switched off my line after only being active for 3 day. This is unacceptable
