I also have received at least one call from a Utah number every day for the past week. All the numbers a within a few digits of each other. Blocking them isn't even helping because they just call from another number.
I keep getting calls from Nephi, UT and Midvale, UT. I also keep blocking the numbers but yet they keep calling back. Of course each time they call, it is maybe 1 or 2 digits that are different. This is getting ridiculous and very annoying.
