No refunds received for cancellation

I have booked and paid for 3 nights ( 13 -16 November 2018) stay at Bayside hotel, Pintown, Durban. I have cancelled the accommodation on the 21 October 2018, prior the accommodation booking date there. They deducted 30% of the total amount for cancellation fee. Up until to today, 6 December 2018, I did not received any refunds from them. They keep telling me to wait. How long does one have to wait to be refunded by the named company.
