TN. Your digital. I'm not. I am however a Patriot Soldier. I just received a call from +53 21 287703. I answered. Some guy says " hold the line please" then it sounded like it was being transferred then hung up. If I knew how to screenshot my recent calls and post it here I would as proof. When I went into my recent calls it reads "Guantoanamo province". Could you please do your digital magic and find out what that was all about? Weirdest thing I've experienced recently. Thank you. Ramon.

Should I try calling the number back?

I'll do my best...we have many friends here.
Maybe one of them knows what to do. I get those calls to. I screen all my calls. I've learned never to answer. I answered one day before yesterday.... they were asking sbout my husband that passed away. I hung up on them. I lectured myself about answering an unknown number...😂
