Male Hiaspanic caller "Alex" said he was with US Pharmacy. Wanted to know whether or what meds I was taking. I asked for companies DEA Registration number- said he could not give but he was legit pharamcy. I told him with out proper DEA or FDA registration number I was not interested. Obviously bogus pharmacy callerr "Alex" was annoyed with me and said "I'd be sorry"- I laughed and said what let me guess I'll get call from imposter DEA/FDA agent. I informend him that I was well aware of the scam that these companies pull and if he persists or if I get such call I will report both his number to FDA and DEA complaint hotline for fraud pharmas.
