Calls me at the same time EVERY DAY, 10:50 AM, I answer and they don't say a word, but I can tell they're still on the line. ANd then they hang up, other times I let it go into voicemail and they leave no messages.
i missed their call and when i called back it was a woman's voice saying "to be removed from the list please enter your ten digit telephone number" i hung up.
