These scammers claim to be calling as representatives of U.S. Pharmacy and state we have done business with them..... WRONG! We have NEVER done business with them. The reps, can barely speak English (there's a shocker!). I immediately demanded his name ("San"), the company name, the company address (which he stated is confidential... seriously??), and a supervisor who simply stated "what's your problem?" Well (lol) needless to say I went into a detailed procession of the irritating multiple calls a day, how they are continuing to violate Federal law by calling a registered DNC number (which is also an unlisted number). They got quite an earful and lecture (until they hung up on me). They have multiple numbers they robo-call from so blocking the number is a somewhat fruitless effort. The only way to get them to stop is to answer the phone, start asking who (specific name) they are calling for, demand a supervisor and continue chastising them as a spoiled, insolent child until they hang up on you.
