The OP is really pandering to the insurance company by his soft approach by phone. Everything should be in writing. He really needs a written final response. They will avoid issuing one for as long as they can if the OP does not press them.
Time, im waiting for them to come back to me as the blame is totally in their court. When they get back to me with a decision then i Will decide whether to contact financial ombudsman, pay them a figure or take it further with a solicitor. Thx for the replies guys as all the advice is highly appreciated
