IMS. When I answered that this was a police station, the accent panicked and said "I'm so sorry. So very sorry. I didn't mean to bother you! I'm so sorry!" and hung up.
Calls the office several times a week. No one answers on the other end of the line, just the sounds of a call center boiler room.
Have no idea why we receive so many calls if they never state the reason for calling.
Just don't answer. If you don't answer they will stop calling eventually. Get a call blocker that is able to block area codes, area codes + exchanges and individual numbers. Don't call them back-also calling back toll free numbers using *67 will not work, they can see your number. Practice self control and it will payoff.
