I had checking and savings accounts with Brewery Credit Union for nearly a decade, but now I've closed them all. Customer service has gone downhill so badly, I've been planning to leave BCU for more than a year.
Apart from unhelpful and frequently hostile clerks, I've been without a working ATM card for over a year. They sent out new ones (for no reason) that never worked. I called many times and they never had a solution.
If you have a problem, you'll often need to go to the office and fight it out there. It's hard to get an answer on the phone, and their phone tree hangs up on you after reading through all the options.
Who has time to waste fighting with their bank to get services that should just work? BCU has been the worst banking experience ever for me, definitely within Milwaukee.
