They did not leave a message and along with 305-368-8339 there was a long line of numbers with some letters in front. I called 305-368-8339 back and got a fast busy signal. I am on the do not call list, shame the do not call list does not work. LOL
The do not call registry is basically voluntary, and is observed by legitimate companies, of which the card service scammers are not included--they are outright criminals, and criminals no not obey regulations and laws. BTW, when you return calls to scammers you are just asking for MORE calls.
