cant subscribe

My subscription that I've had for a few years now has been randomly ended and I'm unable to continue it either paypal or debit card. It just says "We're sorry, but we can't perform transactions to this credit card. Please load a different one."

I tried purchasing a sub through steam but it still hasn't recognized the subscription. Is calling the only way to fix it? 
Account name is Silverstarseaker.

Thanks for any help D:
