I fell for that once, too.
Even went and got a pass word from Visa.
Fortunately, I did - eventually - that same evening - have enough sense to call PayPal. They told me to get a different credit card number and I did.
I sure felt stupid! :oops: :oops: :oops:
The only complaint I have about PayPal is that one kind has to search to find the info for what to do if one suspects fraud or phishing.
