mastercard change denied by 1 agent in florida, and 2 agents in Springfield Missouri.
Orlando told me over next year all sapphire preferred, freedom and slate cards, will be pro-actively swapped to Visa. change was started last week. so now it is even more YMMV.
please post success story and method if swapped from today on..
one agent explained - he selects the "product change" option on his system. in my case my freedom is less then 1 year so it doesn't offer him to change it, but in the case of my sapphire, it offers, him a bunch of cards, it offers the SP visa non signature, (mine is sig) reg sapphire, slate and freedom. he says it used to have mastercard but no longer does.
im pondering whether all their systems are updated at once, and whether some computers are still not updated with this new update.
