I received a call from that number earlier today and they left a voice mail. I called it back and when he asked for my name and number, I asked him for his identifying information so I could verify what agency he was calling from. He said (and I quote) _UCK YOU and hung up. I'm reporting this number to the Maryland Attorney General's Office.
I did also, he was difficult to understand but said his name was Mike something and he was investigating a pharmaceutical company. I see your post was only an hour ago and also from Maryland. I assumed it was some kind of phone scam but I may return his call and report back
I returned a call to FDA Agent Mike Wallace (sp?) at this number. A secretary answered the phone sounding official enough for the FDA and transferred me to Mr. Wallace. He was impatient and evasive and the conversation ended abruptly when he threatened to contact "local" officials. He didn't indicate whether I was a person of interest or a target of his investigation, etc but still I am not sure whether he is legitimate or not. I am going to call the FDA and see if they can confirm or deny this is some kind of scam. I will update accordingly.
I called " Mike Wallace from the FDA back at the number her leftttt 44444444444444444444444434334tq qqqqqqqqqqqqqqqqqqqqq\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
