Double Overcharge - NO REFUND.

I was offered a new subscription around September last year at a lower rate if I committed to a 24-month period, I agreed. They debited my account on the first of October with R2'706.84, instead of R1'047.77. This is R1659.07 more than I should have been debited. I have one primary subscription at the new rate of R850 plus some extra holiday viewing days equal to R195.77 according to my statement from them. I have spent hours on the phone and the matter has been "Escalated" and sitting with "Journals" since last year. My last protracted call was on the 19th of December for which I was given ***4I436 as a reference number.
