Refusal to refund, software doesn't work and now I have to pay more

I signed up with SkySoft, I was automatically renewed for an annual subscription and I then IMMEDIATELY reachout for a refund and was told this was not possible. I decided now to use that software and guess what? It not longer works and I am being forced to pay more to get the Wondershare Uniconverter !!!!!! I am so unhappy, I am again told I cannot be refunded, not can I use what I was billed for. I am disgusted and I don't have the money to pay more.
