REFUSE REFUND ME AFTER I PAID CANCELLATION FEE

on the 23/03/2015 i called to cancel my contract i was given a cancellation fee of R1110.00 however Zubeida confirmed that my account will be debited on the 1/04/2015 for the last time because my of the 20 day notice that is required for cancellation. I paid the cancellation fee on the 23/05/2015 used my ID number as a reference but the last 2 digits were incorrect. I called Zubeida to confim if my payment was received she confirmed no because of the incorrect reference they were unable to allocate the funds to the correct account but i should make provision for the debit order to run on the 01/05/2015 send through my proof of payment of cancellation fee and i will be reimbursed. I done that however Zubeida is telling me i will receive my refund IF approved by their head office even though she assured me i will recieve it. I AM VERY UNHAPPY AND DISPLEASED AT ZONE FITNESS I HONORED MY CONTRACT AGREEMENT BUT THEY REFUSE TO DO THE SAME I DEMAND MY REFUND I WILL NEVER REMMONED ANYONE TO THEM I WILL ENSURE THAT ALL YOUR FACEBOOK AND TWITTER FANS ARE AWARE OF YOUR DISGUSTING SERVICE TO YOUR CLIENTS.
