Update to my previous message: They left a voice mail which appeared on my phone long after they called (i.e., my phone co's (TracFone) fault). The woman claimed that "Floyd" had ordered "siding" and they needed to verify his account. It seems reasonable that they misdialed my number, or "he" gave a bogus (my) number, for whatever reason, but, either way, I am not returning or answering the call.
