If the payments your making arn't being used to pay any off this financial year, then after a few missed payments they will normally ask for the full amount, rather then just the missed payments. They do it because it's cheaper for them to get a court summons for the full year, then to do it every couple of months if payments keep getting missed.
If you give them a call though I'm sure they'll agree to another repayment plan.
