Over the course of several months a single number to Pine Ridge, SD, has appeared on my VZW bill each month. The call orginates from the same city in my state (which I do not live in nor visit). It appears almost daily and is for only one minute in duration each time. I called the number, and it is a voicemail that "is not setup correctly." Ironically, the calls continued from the location in my home state, while I was in Canada. It is not plausible that I made the calls on my device, since I was hundreds of miles away from the location for over a week. (Yes, my iPhone Xs was with me.)
I am not charged for the calls; however, I am concerned that my number is being used for nefarious reasons.
Any ideas of how to combat this ongoing issue? Thanks!
