If you have caller id, keep it logged in your phone and maybe take pictures of it or something and then call the phone company.
I did call them and they did not understand. The only thing they say might of happend is that the person that is calling -if from a business and sometimes businesses have certain exceptions? This is a very small business and I did not understand that and tried to find that out and haven't been able to do that. This isn't a business related call either they were calling for something else.
Call your phone company. You need to hold them responsible since you have the call block service. They probably have a computerized fix for the glitch. It is their lines , you pay your bills, make them work for you.
I hope it works out. I have had the frustration of unwanted callers.
