Just FYI, we're having problems too and I called the mortgage company first. The reduced ur payments by half for 2 months which really helped.
My H has had to sign on at the jobcentre and they told him that some mortgage companies will tell you it's ok not to pay then put you as defaulting the payment so you have to stay with them.
good luck
