Horrible service from Rain

I called rain on the 24th of March to reactivate my account with them. I asked the lady I spoke to before making payment if I would be required to pay again on the 1st of April of I paid on the 24th of March and she said NO. Now to my surprise I got an sms that my internet would be suspended as I did not make payment. I called so many times and was made to hold for long than 3 consultants hung up the phone without assisting me. The 4th one promised to call me back nothing even now. Please explain why I would be charged R529 from the 24th of March until the 1st??? Why was I not told to wait for the 1st to make payment. This is totally unacceptable, I need my money back or reconnect my internet. Or else calculate how much it would cost to use your internet for a week and refund me my balance. Your consultants are the worst
