Refusing to refund client and they do not have a cancelation policy

They are refusing to refund people their booking money and they do not have a cancelation policy. I cancel a event a week before the date of the event and asked about their refund policy and they just said they are not going to refund. I asked them to send me their policy or tell me where to find it on their website and they just did not respond for a week or 2. When they finally responded they said they will refund me only 50%, I just agreed cause it's better than nothing and that was a week ago. Follow up on the refund they told me to email my baning details and I did as requested a few days later I asked again how far they are it the refund. I was promised that by Friday it will be sorted, I followed up yesterday but I only got blue ticked on Watsapp which is what they have been doing all this time.

I would understand if they have a refund policy on their website and I just didn't read it but to say no but they don't even have anything in writing when it come to refunding. They told me to postpone and I told them I couldn't cause this was postpone a couple of times already due to the funerals we had in the family. The reason why I canceled is because I couldn't reach the minimum required number of people the venue take for me to host the event, so I decided to host it at home
