I called Minimed on Tuesday about my pump not working right and they said that they were going to replace it. I should have recieved my new pump on Wensday morning, by 10:30am, that's what the man who I talked with said. Well it is Saturday morning and I still haven't recieved it yet. I don't know what is going on, but I'm going to have to call them again. Anyone else had a problem like this?
