About a month ago, I got a phone call from an unknown number. Upon picking up, the person said verbatim, “Sorry I am having difficulty with my phone. I will call you right back”. They hung up and about 30 seconds later they called again. Curious as to what their next move would be, I picked up. They said the same exact thing, “Sorry I am having difficulty…” and hung up again! About 30 seconds later, they called again. This time I ignored the call, and they never called back.
They made no attempt at phishing or to sell anything. At first I figured they wanted to verify that they were contacting a valid phone number, but then why would they call back? Additionally, I haven’t since noticed any increase in unsolicited calls. Nothing phishy has shown up on my phone bill either.
