I got caught up with the bad data migration and as a result ended up with two sets of numbers and two sets of CURPS, with Tia's guidance and my standing in several lines and some excuses as to why there were delays in sorting the mess out (along with a 1600 pesos payment) it finally got totally sorted out and a new card issued. Tia definitely knows the system and how it changes from month to month. You only can consult someone who is in constant contact with the system, just because someone goes through the process (last week) does not make them an expert, trust me on that one.
