Vitality Cancelled

So I take out Vitality for gym with Virgin Active and pay R750 monthly, the 12 months are up and I request to cancel which was done. I then contact Virgin and they confirm they cancelled it on there side to and last payment is 01 May 2019. So instead of taking the R750 they debit me R2400. Ok... so now the blame game start. Not advised from Vitality or Virgin of this amount debited. Virgin says I was put on normal rates and the instruction came from Vitality and they cannot refund unless they get the go ahead from u guys. Im not going to threaten as this experience has left a bad taste as my bills are always paid. All im asking is that you refund me the R1650 or give Virgin the instruction to do so whichever way is quickest...If whomever is reading this cannot fix it, please direct my complaint to someone that can.
