I actually picked up when this guy called. He refused to talk to anyone but the homeowner. When asked, "what is this involving? if it is important I can go get him," the person simply repeated his request for the homeowner. This exchange happened multiple times before he asked me if I was the homeowner. I told him I was not and he said that is fine and he hung up. Upon calling him back, I came upon an answering machine that you could not leave a message on. The company on the answering machine sounds something like "de marketing solutions." I have no idea who they are. Googling them reveals nothing. The only companies listed in waldorf, md that are even similar to that is: DeCurtis Marketing Solutions. Hope this helps other people track down this annoying caller.
