I have been receiving 3-4 calls per day from this number, but have not been available to answer the calls. Regardless, I have called the number and, like others have said, am able to only enter my # to be put on their DNC list, or leave a message. After calling many, many times and keying in my number, I left a message asking them to stop calling. Still getting calls 3-4 times per day. So, have decided to just keep leaving messages. Funny thing, though - every time I call to leave a message, all that seems to come out is a very LOUD whistle. VERY, VERY LOUD. It must be very annoying for them. Almost as annoying as being harassed several times a day.
