After getting 3 - 4 calls every day for weeks I finally answered it. It was some guy from a call center from India claiming to represent a mortgage lender. I told him I wasn't interested and to never call my number again. He gave a big sigh and hung up. Reported it to DNC.
They keep calling over and over at least three times a day. When the answering machine picks up, they hang up. When I actually answer the phone, it goes into a dial tone and disconnects. This is very frustrating. My "zapper" isn't blocking it.
