Paid a contract for more than 12 months, didn't even utilize the service.

Our Standard subscription contract was signed on 5th May 2015 and the first debit order went off on 1st August 2015, the debit order was supposed to be stopped since it's a 24 months contract. Unfortunately, in this case, it still went off until Nov 2016. With all the payments we have done, we have never used any holiday not even the free voucher we received on the evening of 5th May 2015 at your Presentation as we were always told that the resorts we wanted to book were fully booked at our requested dates and so went a full year without us going for any holiday after paying R279.00 for 15 months. Please refund us our money as we didn't utilize what we paid for. The last email I send to one of your consultants was Nov 2016 when I asked if we could still utilize our holiday package even after the contract expired, seeing that we have already paid for this for 15 months, I never received any response.
