Hi Beetle,
I have moved your post to start a thread of your own.
Welcome to CAG. The first thing you need to do is to open a new account. You can find out info on banks which offer accounts to those with a less than perfect credit record here:
Do you need a parachute account?
It would then be good to do a Subject Access Request to find out if they have applied any charges in the past and how much so that you can claim those back. If they have entered a default on your credit record as a result of charges you can apply to have this lifted also.
Have a good read through the FAQs and
step-by step instructions before commencing your claim.
There is always plenty of help around should you get stuck.
All the best
Zoot
