********** UPGRADES

I recently received an email that I've upgraded to 4G unlimited and will be billed R479!? I did not sign up for an upgrade and neither did I use my 4G 19 hour off peak sim this month? Who do you speak to at this place as there's not even a single Call Centre agent available. You receive responses 2 days later. I was advised in response to downgrade the 1st of Sept?? Who will be paying for this overpriced R479 on the 1st as I did not upgrade in the first place... Or is this your way of making money for me not using my sim this month??? I WANT TO KNOW WHO DO I CALL??????? IF I DO NOT RECEIVE A RESPONSE & THIS IS DEDUCTED FROM MY ACCOUNT, I WILL POST A NEGATIVE REVIEW ABOUT RAIN ON EVERY MEDIA PAGE I CAN THINK OFF!!
