Likely a robo call. I answered phone, could hear lots of talking in the background like in a call center, and after a couple of seconds a male with a heavily accented voice (maybe Indian or Middle Eastern) said he was calling from the U.S. Pharmacy. Wanted to sell me prescription medications, especially wanted to sell Cialis. He got angry when I told him that I didn't take any prescription medications. He asked me, "Why not?" I get at least 3 or 4 of these same type calls per day. I've never purchased any prescription type medication Online or through any Internet pharmacy. Total scam calls from a foreign country. These guys are relentless and change their phone numbers hourly or at least as the telephone numbers appear on my caller ID. Total scumbags!!
