Gap Cover not all it claims to be

On 1 Feb I submitted a claim for a shortfall in a hospital claim to Xelus. Since this time, KX has been sending me many requests for additional information on a piecemeal basis. They request one piece of information, you provide this, 3 days later they request something else and so it goes. they try to do everything possible to delay your claim and tire you out, short of repudiation, to prevent you from taking them to the ombudsman. So far KX has made 4 different requests for information to me, each one having a turnaround time of several days. I have given all the information I have and they could possibly need, still they continue to procrastinate.
