Are you wondering why you can't buy anything from Wordlinx using Payza funds?
It's very simple, Payza have withdrawn their services for all UK-based users. I'm guessing that Wordlinx didn't have time to remove all of the Payza buy buttons on every page yet and that's why we still see them.
Well, this makes me worry about Payzas future. I haven't been able to withdraw my funds in a very long time now and less and less sites are letting users use Payza as the payment alternative.
