Don’t be too hard on yourself, or mistrusting of everyone. Presumably, you did get your updated documentation. It’s when you get scammed out of your money for nothing that it would really hurt.I also received a letter from Maritime Documentation Center and fell for their scam as well. Looked like they were a 3rd party vendor for the US Coast Guard- with our Official Documentation Number. I wanted to report them on every forum that I can — to warn others from falling for this. From Now on - I will be much more careful and less trusting.
I do wonder why these folks haven’t been prosecuted for mail fraud. Although, the mailers do seem to have been changed to walk the line.
