When I make a purchase from a site that accepts PayPal, I am suddenly unable to select PayPal Credit as a funding source when I click the Change link. The PayPal Credit selection is grayed out. My account is payed up and I have a credit line of $2000 which is far more than the amount of the puchase. This even happens if the site has a PayPal Credit button.
I have emailed customer service twice about this. Both times, all I received were static responses suggesting things like unpaid balances, the site may not accept PayPal, and similar things that don't apply. I've also called the customer service phone number. It's apparently fully automated and does not give any opportunity to talk to any customer service personnel.
If you are persistent with phone calls you can talk to an agent. Unless there is a technical problem, they will not likely provide more than a general response as PayPal will not disclose details with security models.
It could have something to do with the merchant, the product, the country, your account, your creditworthiness, your finances, or something else. You are the only one who know all of that information.
