Am not sure if this is the latest robocall spam/scam.
Call from 800-309-0524 with recorded announcement to upgrade my credit card terminal to be compliant with some scary sounding acronym.
I don't have a terminal.
When the callers are:
a. Vague (don't identify a company you do business with)
b. Recorded
Run.
