if # is blocked, they will consistently switch numbers. You'll quickly run out of room (limit 100 on my phone). This slows them down for about a day or two, as numbers seem randomly generated...
Female caller calls everyday, leaves no message. I answered call this morning, asked name, she said Amanda Woods. I asked her what company she was with and she said this is a business call for Brian. I told her I was Brian's wife, she said the call is for Brian. I told her she is a telemarketer and not to call our number again. Call sounds like an overseas call and foreign female caller.
