I had already entered area code 904 to my call blocker as a result of similar nonsense months ago so I was undisturbed by this new batch of parasites.

Do yourselves a favor folks and get a call blocker.  Sell a kidney and/or first-born if you must. :-)   I used money that I might have otherwise contributed to annoying political parties and charities.  After the constant calls, I decided to put the money to better use.  The resulting absence of annoying calls is worth it.
