Her Sisters screwed my husband and me big time. Promised to provide us with major help. Even had us travel to their convent in town for a few meetings to go over in detail how they would help us. Long story short. The superior was transferred shortly thereafter. Apparently, they are so disorganized, what one superior does has no bearing on the next one that is assigned to the local convent. We never heard from again. The Missionaries of Charity left us hanging and in limbo. When they never showed back up again, I realized we weren't going to get what they promised us. No use trying to call them either. They have the oddest schedule. I should have gone to the local newspaper and made a big stink about it, but I just let it go.
I had read a while back, when Mother Teresa was beatified, the MC's doing the same thing to the person who had an alleged miracle (which was no miracle at all according to the doctors who took care of the person) through the intercession of Mother Teresa. I didn't believe it at the time, but they did the same exact thing to us, so apparently this isn't uncommon behavior for them.
I don't think she should have been canonized. Not because of what her religious sisters did to us, but because Mother Teresa didn't do anything extraordinary. By that I mean, they act like no one in the Church before her ever did what she did.
