Bender......bank was informed of dates.
All others........after email & verbal conversations, it was found that there was a "glitch" in the system from my bank/VISA/Mexican banking system. tried the ATM this am and all is well today. got more $$$ than needed just in case it happens again while we are here. but will add this experience to the travel info vault and WILL NOT LET IT HAPPEN AGAIN.
Technology, ain't it a bitch!
