Don't pay any more money
Get a portfolio of all the transactions you have made with Welcome Finance - times of telephone calls, what they said and keep all letters.
Write to Welcome Finance (Recorded Delivery) and state you are not willing to pay another payment and request the agreement and any other correspondance. If they threaten you with Court action 'Let them' this gives you a chance to speak to the judge and explain the situation to them include the history of your husband being made redundant.
If you don't get the answers even if you don't like them you need to stand your ground. You stated you have a CCJ against you, where you informed of the court action before the judge granted a CCJ - did you like so many people bury your head in the sand and ignore it? becaus if you where not informed then you have grounds to maybe have the CCJ lifted - You have to remember the CCJ is on your credit report for 7 years (I think) after you have paid the debt so this will effect your credit history a lot longer!! - check your report with 'Experian'.
DO NOT USE DEBT RECONCILIATION COMPANY - GO TO THE 'CAB' WITH ALL YOUR DOCS. As the company you spoke of have done no work on your behalf you are entitled for the money back (£100) as long as no agreement was signed.
LAST THING - Judges will be more simpathetic to you 'The Consumer' than the supplier. A little tip: If you are having difficulties paying a debt - sit down and write out a 'means test' i.e. what you have coming in and what you have coming out.
1. List all debts - check each debts interest and then clear the highest first.
2. Pay your essential bills such as Gas/Elec first (You need to live).
2. You can have the interest stopped whilst you are in dificulties - speak to the courts they will advise as there is a form you fill in (Don't remember the name but check it out, it might cost you a fee)
3. Only pay what you can reasonable afford.
4. Write to your creditors and explain what has happened and state in your recorded delivery letter that you can only pay £10 per month for the next 8 months. If they threaten to take you to court 'Let them'. You have offered to make a payment therefore the Judge will be on your side.
It is very difficult to advise as I don't know all the issues relating to you. BUT please don't pay out anymore money to any get quick fix promises to clear your debts companies and NEVER sign anything until you have had a cup of tea and slept overnight on it and ofcourse read the small print. GOOD LUCK
