I believe this is a number from an ophthalmological magazine service. Have asked them numerous times to take me off their list, but now instead of a person being on the other line it just clicks and then turns into a fast busy. Calls about twice a day.
Have been getting 1 to 2 calls a day from this number for the past month pretty much the same time every
day usually in the morning. I never answer and they never leave a message very annoying it needs to stop.
