I spoke to my bank after getting the 'Unknown Error: Card Declined.' I wanted to make sure that there was nothing from that end that would be causing the error. I was told that my bank has excepted the charges but that the request is for $0.00 and not $3.99, meaning that it there is no problem with my bank or my card.
Also cause I know there will be some people that I have to be clear with. I have put my card information in correctly, other wise my bank wouldn't be getting the request.
I also get the same results when I try to pay for a year long subscription of the $29.99.
