I keep getting calls from this number early in the morning & late at night. They won't talk to my answering machine and I don't know the number. I don't owe anyone, so if it's a bill collector he needs to find the correct party & stop bugging me at all ungodly hours. I am disabled and can't run to the phone for solictors, etc.I am on a do not solict line. How can we stop these calls?
