Cancelling of deal and refunding of deposit

We bought a vehicle from Imperial Germiston. The vehicle was sold as a 2015 and when we received the service book it was fount to be a 2014. On Monday 26 October 2015 we informed the dealer that we would like to cancel the deal. Before our deposit was refunded we asked that the cheque be banked with special clearance and that we would pay the costs of doing so (R 80.00) Our deposit was refunded on the 30th October 2015. Today, the money is still not available in my account. We are still waiting for the cancellation of the deal to be completed as we speak. We have asked for the special clearance on the cheque because we need to pay the deposit on the other deal we have. Today is the 7th day that the cancellation is dragging on. <br> This is unacceptable to me. Does it usually take this long to have a deal cancelled??????
