Same thing happened to me! It was a lady with an accent. Is TW Cable giving out numbers of their customers? As Julie indicates, she got the call only after signing up for TWC, and that's when I began getting the calls as well...
Got a call at my office from 1 310-201-4562. the guy sounded out of it and wanted to sell me cable. I'm like, no thanks and who are you with Mike? he hung up on me. curses
