Momemtum trying to find ways not to pay

Being a customer for over 11 years I really thought they were a great option on life insurance. That was until I had to claim on my policy for a critical illness. 18Months ago I was diagnosed with a life altering critical illness. After consulting a specialist I was given a remote chance of recovery. However this did not happen. I did not not respond to any medication or prescribed treatment. Thus now was a good time for me to file a claim for critical illness as per the cover on my policy. So on the 1st of Feb my claim was submitted. Almost immediately I received an email confirmation of my submission and the process. But that was the last of good customer service. According to policy I would have had feedback within 10 working days. So on day 9 I called the risk claim center. Oh, my claim is still in process of assessment. Being promised I will be kept up to date through out the process was all but true. Numerous emails and phone calls from me was the only feedback ever received. 15 days later I managed to find out whom the claims assessor was working on my claim. Called him directly on the 19th only to be told my claim was not discussed with the medical officer. Claim denied.
