The number is for a company listed as "Tax Defense", based in Rhode Island. Guess they have a list of late filers they call. I got called for an extension, and am all squared away. Think their info was old. :)
Robo call from "Tax Defense" offering to help reduce or negotiate paying off back taxes. Funny but I've never owed any back taxes. Recording asks you to push #1 to speak to a rep but every time you do you get another recording saying 'All reps are busy' and it then tells you to leave your name and number and stresses several times to "be sure to tell us how much you owe in back taxes!".
If you call back the 401-365-6294 directly you get another recording saying "if you want to be removed from our calling list press #1"
