Sarah 76.
Sarenco {let sleeping dogs lie} is good advice.
Cabot seems to have taken over a lot of Bank Debts, such as yours . With house sold your shortfall k160 is now classed as unsecured, that means that unless you have other assets , work , or good future prospects there ain,t much point in chasing you.
Cabot may well (within 6 years from last payment on your old account) come asking questions, if they do write/contact you.
Cabot seems to have problems in getting info on accounts , so You come back to AAM before doing anything.
In particular don,t identify yourself on any calls.
