Slammed the phone in this idiot's ear as hard as I could.

Calls office multiple times, but no message left at any point. Not a number from my company or contacts.

called on behalf brian maxin from logi analytics but couldnt disclose why they were calling or leave a number for me to contact this "brian"

Called my company line.  Asked if I was XXX.  I said wrong number and hung up.  They called back.  I didn't answer.
Phone ID had "Tiburon/TI"

Stated he was the assistant to someone and needed to speak to a colleague. When asked what it was regarding, he stated he wasn't at liberty to say. As she was in the office with me, she approved via speakerphone. When the other person got on the phone, he asked if this was another organization and then said he had the wrong number and hung up. (Call was repeatedly muted to attempt to hide 'call center' background noise. Both people on the telephone had accents from India or Pakistan.
