when you open a new account the deposits are held for 6-10 business days. This tiny bit of info is buried in the welcome package somewhere. If you need access to your money forget about it and no matter who you talk to you get a different story. Customer service doesn't exsist.
Don't even think of opening an account with M&T Bank. The customer service is horrible. In my opinion, this is the worst bank I have ever had to deal with. They freeze your account, close your account, charges annoyingly high fees and they don't even bother to inform you. This is my personal experience, learn from it and stay wise, rather than going through what I have gone through.
They're so bad i cant't even waste another minute telling you about it after i spend so much time calling branches and the 800 #. Bottom line is they suck! Also i put one start because the website made me. In my opinion they deserve no stars. Two thumbs down!
