Poor customer service

Poor customer service their line cuts after 15 minutes of holding 3 times! The advisors pastt you pillar to post wasting my minutes as I spoke to thsi people for 3 days and got no where. They never leave notes and the next advisor handles the call without care or empathy. I asked I call back as I got one minute left they advise they can't do call backs! Wish I never changed banks. They quick to send a letter to say you missed a payment but never sent the letter r notifying me about the increase!
