How do I track down what could be a bogus PayPal charge?

My late husband’s checking account was debited $100 today. I managed to get into his PayPal (never done that before) and saw that it said it was an automatic billing to the Washington Post.

What does the Washington Post charge $100 for?

I’m not sure this is real because when I clicked the link to manage the automatic payment, it said there wasn’t one. The debit was real, though.

Can an entity use a bogus ID such as “The Washington Post” to charge PayPal for something? I mean, could my husband have left a recurring charge in place that was using a false name? Can someone open a PayPal account and make charges calling itself “The Washington Post”?

I opened a case with PayPal to find out what this charge is and request a refund, but I also want to stop any other such payments. They may not report back for six weeks.

I’m way out of my territory here and not sure what is the next step. If I disable the link from PayPal to his bank, does that close the PayPal account? and then how would I get a refund? Do I go to the bank and stop payment, or is it already too late?

One of many posthumous surprises from my late spouse.
