I received a letter from Student Loans Company about repayment

I received a letter from the Student Loans Company concerning repayment of contingent loan. They've stated that they want documental evidence that I'm getting job seekers allowance dated within the last 3 months, but I only have evidence that was dated last September - a confirmation letter that I'm eligible for jsa.

I'm stuck. What should I do with this situation? Should I just send this evidence anyway? Thanks.
