Do Not Like The Way They Do Business

I belonged to the same credit union for over 8 years and the one before that for over 10 years and have never overdrafted.  We are avid users of online banking.  We switched for location purposes to ECU on a trial basis a couple of months ago.  BIG MISTAKE!  Their so called "Real Time" checking account was not explained to us when we opened the account.  No brochure or materials were given to us explaining how they post things to their checking accounts.  Their online banking is useless.  It shows nothing actual and does not agree with what a teller sees on their computer system.  The other day I had one balance on online banking.  1 hour later I made a deposit and the slip showed another balance which did not correspond.  Then 1 hour later my account showed yet another number.  Impossible to keep up with because you can't see everything!  A business over-charged our debit card by $1,000 and we did not know it.  All we could see was a big difference in balance and available balance on online banking.  I had to go to a branch to find out exactly what it was.  They said it was corrected by the business immediately.  So why put a hold on our account for the mistake amount?  It never showed up on online banking or on our statement later.  I asked to speak with a branch manager and was told I had to make an appointment!!  I called what I thought was a branch and got a customer service center.  When I tried to get someone to explain how their posting system worked, I couldn't get a straight answer.  Not sure the CSR understood it either.  She proceeded to hang up on me.  ECU has forgotten it is supposed to be a local credit union, not a large national bank who does not want to serve customers, just take their money - the reason we have always used credit unions instead of banks!
