1. Whatever you do, don't go to any of the outfits that advertise on TV or the internet. They all end up costing you money one way or another.
2. You talk about a "credit management service". Do you mean a debt collector acting for the bank? If not, who are they and why are they chasing you?
3. You can have a bank account while you are bankrupt. It would be a basic account (from Nationwide, Co-op or Barclays) with no cheque book or overdraft facility, but your wages could be paid into it and direct debits set up. However, your debt (assuming the �2K is the only one) is really much too small for you to consider bankruptcy.
4. You need to make arrangements to pay what you can afford based on an income and expenditure statement, which needs to be supplied to the creditor or their agency. Once you have put forward a proposal you should pay the amount each month whether the offer is accepted or not. You also want to get the interest/charges frozen if possible. If you can't get anywhere with this yourself, get free help from your local CAB, or from CCCS or National Debtline.
