Horrible Service. Rain Wifi Debited me after I cancelled

on the 4th of Aug. I called Rain to cancel my subscription. It was noted and added and I received an email to say that they have added the note on my profile. Keep in mind i have been calling and making sure that this cancelation is active on my profile Today on the 25th of Aug, they debited me. I go on the website, Leila the agent who could not help me the first time. I ask her to check my profile again as my cancellation went through, why am i being charged R555 after I cancelled. The service is terrible. I want to cancel this rain wifi as it has been the worst. I also want my money back. Why am i being charged when I had requested a cancellation a month back.
