Hi, Frankie.
Unfortunately, I do not have any payment option other than PayPal at this time. I am kind of stuck with PayPal for the time being due to tax and accounting reasons, but I am looking at other payment options for cases like yours. I know that does not help you in this regard, and I apologize.
Have you tried talking to PayPal about why they won't take your credit card? Might be a simple fix.
Sorry about that, bud!
