Bad service and inconvenience

I am experiencing an inconvenience at this resort and receiving the worst service. I checked in on Friday 10th June and was advised that if I pay inventory deposit in cash I will receive it on check out in cash. I have advised the staff at reception that I need to check out by latest 6h45 tomorrow morning and they have told me I will not be refunded in cash as they won't be in. I an now forced to vacate my unit a day before due to the inconvenience of their inventory list and them not willing to accommodate my situation. They flat out told me that if I leave before 7h30 I won't get refunded tomorrow. I was not told on check in that I cannot check out earlier than 7h30 or I'd not get my cash back. I was told if I pay cash I get cash back. Now all the inconvenience falls on me. This after paying for a full week at this resort. I am now forced to drive back to Gauteng a day before my check out day. I'm staying at unit M44.
