Problem with Adding My Card

I got my EON debit card last May 9 and didn’t find the time to add this to my paypal account until today as I have other account care of my sis in-law. As I’m verifying my username and passwords in Union Bank my transactions went smoothly but when I finally add it to paypal the following lines appeared on my screen:

This credit card has been denied by the bank that issued your credit card. For details on why your card was denied, please contact your credit card issuer's customer service department. Or, you may want to try adding a different credit card.

And even when I tried it again twice it didn’t work, I was talking to and scolding myself why I didn’t add it the last few days. I was so busy with my work, my blog, my family and the coming school opening the reason why I always put some things behind me. Anyway I called customer service at 84-186 (works only in PLDT phones) and CSR Sandra assured me that there’s no problem with my card it’s just that they are currently experiencing connection problem with Visa. She told me to try adding it again on Thursday, no commitment! Meaning not sure if it will work, hmm! What a day! To be sure I'll try everyday :-)
