LMCU called me yesterday. The guy indicated to me that they had an issue with a member using mobile deposit in a fraudulent manner so they are disabling that feature on my account as I deposit "a lot of these" but that I am welcome to mail them in
So no account closure (as of yet) and they claim they just need the actual money order from now on
Not sure whether I will bother. I am 2.5 hours from the nearest branch so that is pretty much ruled out
