Bad service SANPARKS

Had a double booking which I cancelled. Requested a refund to my bank account in the 21st of November. Still no reply on any of my emails requesting updates on the matter. When you phone you hold for over an hour as caller number one. The one time I did get through I was advised that the refund will take place the next working day which it did not. I can only imagine if this is the level of service international guests receive from our biggest tourist attraction in the country it can certainly have a negative impact.
