Bad worst nightmare experience

Good morning I had booked for accommodation at Riviera on Vaal resort I was attending a friends wedding.On the day of the wedding early hours of the morning I received a call that a family member passed on I had to leave the place now my problem is they don’t want to give me a a refund or even a voucher of some sort because what had happened it was beyond my control now they are telling me I have a week to utilise this voucher otherwise I will forfeit it I did not even get an email formally from the hotel nothing all I get is a phone call full of threats about me coming there I was not even happy about the accommodation the sealing was falling off it looked ****key and the food we ordered was terrible I am so disappointed. And I had paid a lot of money around R3000 something this was the worst nightmare.
