DSA done and dusted 2 years ago

i had a DSA done November 2017,voted on by the creditors,passed and sanctioned by the courts.

i recently decided to get my CCR report and Cabot Financial have me down as still owing them money even though they got paid out in the DSA.i also obtained my ICB report and there was nothing on that from Cabot,very confusing.

need a bit of help on this one as Cabot are really messing me up.
