I really don't like my bank right now!

First off, they decided to change our debit cards from Visa to Master Card, without really telling anyone. My sister told me about it, because her debit card was denied. Because of my move, I had a heck of a time actually getting a new debit card. I finally get one in the mail a week or so ago and my pin number still has not shown up. Stacy and I go out for dinner on Friday night. I wanted to pay for her dinner, because she has done so much for me since the whole move. Yeah, debit/credit card is denied. She ended up paying for dinner, but I had enough cash to pay for our beers the rest of the night. We went to a local dive bar...I don't know if they take anything but cash. We got our butts kicked in shuffle board, but that is another story. Anyway, I call the bank Saturday morning. They said my debit card was not associated with any account. Great! No wonder it didn't work. In the mean time, I have transferred money from my account to an account I share with my sister. That debit card works. Only problem...transfer still has not shown up. When I look at my account online, it says both of my accounts have money. When I try to debit money, it says my account is negative. I just want to get some money! Somebody please help me!!!!!
