I've been getting their calls for a while now and have ignored them, but today I answered and they hung up on me when I told them my son-in-law (whose name is on the account) was not available. I called back and asked them to remove the number from their calling list. I refused to give them our address, which they asked for in order to locate our number. Apparently, they have people who go door-to-door to collect information. At least in this case there's someone on the other end!
