Bad Service - Unresolved Claim

I put a claim in Sept and Nu Gen Plumbers were assigned to carry out repair work at my home. The have messed up the repair and have abandoned the work. I contacted Outsurance who sent out a company to inspect the work. Jerusha Ragavan has been very helpful in trying to resolve this but I think she is limited with what she can do. Outsurance as a company has to resolve this issue now. The work should have been completed by Sept 13 . Its now nearing the end of November and the work is not completed as yet.
