Maybe I found a smoking gun.
An hour or so before all these calls started I enrolled in Walmart Pay, which included providing my cell phone number. No way to know if that is the source of the sudden explosion of robocalls, but the timing is suspicious.
I'm going to try to cancel the account but I think Pandora's box is already open.
I had a marked increase in spam phone calls a few years ago when CVS absolutely INSISTED on having my cell phone number if I was to get a flu shot there. They already had my land line number, but claimed that Medicare required my cell phone number too. That sounded fishy to me, but finally I gave up and gave it to them. A few days later, I started getting (seemingly unrelated) spam phone calls. I asked a manager to take my cell phone number off my account, and they did, but the calls continued.
My wild guess is that in my case, it was the individual employee, not CVS, who sold my cell phone number to spammers.
The silver lining to the cloud is that the calls slacked off in a month or so.
