Limewire Pro

[Iggy]

Apologies if this is the wrong forum.
I signed up for Limewire Pro yesterday and it said that my card was not accepted it gave me multiple reasons why but none of them applied to me.
I went back and filled out the information again and still it said that the card was not valid.
Today I called my credit card and found out that low and behold $18.88 was taken from my card two times...but I *still* don't have Limewire Pro.
I go to ask for help by clicking on Billing Inquiries ..it wouldn't accept my email addy I used to (try) to get Limewire Pro.
So basically I have paid two times for Limewire Pro without actually getting Limewire Pro...and the website telling me they couldn't accept my card.

Any suggestions?
TIA
