Wikideal Bad Service

I have been purchasing Wikideals for some years now and when I had previously requested a refund, it was processed with a small cancellation fee. I booked accommodation and need to cancel. When I called, I was told it can be cancelled since it's within 7 business days but will cost R25 admin fee which I said is no problem. When i called again to check on refund, they said they need confirmation that i had not stayed at the place. I have emailed them & tried calling but not getting a reply.
