Two calls from them in two weeks. Each time a middle-eastern sounding person claiming to be from VMS I believe. Each time I told them to put me on their do-not-call list, and that I was registered at www.donotcall.gov I have filed a complaint each time on the do not call website as well, and would encourage everyone else to do so as well.
They use an autodialer, causing a delay after you answer your phone before they respond.
