should I just stop communication - if I do will they persue the courts for payment? or should I e mail them something ???

they did send the credit agreement, with the letter

the debt was signed 26th april 04,

Hi everybody I hope you can help me ! This all started over 1 year ago and has finally (or so it appears) come to a head but I really need some help and advice. Dlc wrote to me over 1 year ago claiming a debt from Egg card of £2,000 from 2004 was mine - I disputed the debt at the time and heard nothing back. I then received another letter from lowell finance stating the same, threatening to take me to court, again I disputed and asked to see the credit agreement, after a few letters, they too stopped communication. I then received another letter back in September 09, 1 year after it all began - from Ruthbridge Limited - stating that they were dealing with the debt and full payment was requested. I e mailed Ruthbridge disputing the debt and informing them of previous communications and asking to see a copy of the full credit agreement. I have now received a "without Prejudice" letter" together with the credit agreement - stating that I have to pay the debt in full by the 15th April or they will persue bankruptcy. I am a little worried although I am fully aware of their bullying tactics. Can anybody please advise me ?? thank you !
