They constantly call for a co-worker of mine who doesn't work in my office and works in a different location. On several occasions I have given them his office number and told them he doesn't work in my office and yet they still keep calling my office. I am not giving them any other numbers because honestly, it's none of my business what my co-worker does outside of work. If he doesn't pay his bills, it's not my issue. Next time they call, I am going to make sure they understand that constantly calling my office isn't going to get them anywhere. I will "politely" ask them to stop calling and tell them I will report them to the FCC if they don't.
