We moved to co-op bank in January, we have a cashminder account with no overdraft because our credit rating is knackered.

We are on a debt management plan with CCCS.
We've had a couple of times when stuff went unpaid and this month they've paid the items and let us go overdrawn. Of course they have also charged us £19.50 each time.
Each time it was "our" fault - One time I'd forgotten to transfer money from my Co-Op account into the Joint account, the other time I transferred enough to cover bills that I knew were coming out, but my partner took money out or spent on his card

without checking with me
Yesterday we got a letter saying "please pay in enough to meet all future items... to discuss the matter further or if you are experiencing financial difficulties please phone blah blah blah..."
Today we got a letter saying "as your account is not being conducted in a satisfactory matter we no longer wish to retain your banking business. I am therefore giving you 30 days notice of our intention to close your account"
We had trouble opening the account with Co-Op in the first place. We got turned down by Barclays and NatWest, I'm worried that we won't be able to get another account! Can they really turn round and change their minds in a day?
