Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
Why did you go abroad; was it because of your husband's employment? Were you living in job related accommodation whilst you were overseas? Did you send a Form P85 to the tax authorities when you left in 2010?
Once I know this I will be in a better position to respond to your query.
This is a duplicate question. You should approach Just Answer Administration for a refund.
