I want to sell some of my UPS stock the only problem I have is that since I don't own 100 shares I can't do it on line. The form I downloaded from BNY Mellon requires a Medallion Signature Guarantee. I went to my local bank and they don't do that. I don't think they even knew what I was talking about. Whats the easiest place for me to get this done. Very frustrating!!!
