In essence, and if it helps, I'm hoping they may agree to full and final settlement? If this figure is less than the amount stated by the Court, but Safeloans agree to it, will that be the end of it?

Hi, I have a letter dated 26th October from Northampton County Court for the sum of £430 - I understand I have 28 days to pay this sum in order that a CCJ will not be logged against me. I am in a position to pay this. However, as the loan amount was nearer £150, is it now too late to dispute the amount with Safeloans (i.e their fees), or would I still be in a position to negotiate a lower payment to them to avoid the CCJ be actioned? Hope this makes sense! Thank you in advance for any help! Neil
