No effort made to pay policy

Policy for lifecover taking almost a month to be paid-i submitted all claim forms with medical history from the doctor as per the request-i have been calling since the 10 day assesment period has passed to query the progress only to be told momentum needs more medical history from the hospital and the doctor who treated my gran. What I fail to understand is that the doctor completed medical history dating back to 2008 and I submitted forms from the hospital where she died-momentum says they need more information as the policy was under a year old-so what are they saying that It could be **********-HOW??? Or maybe they are trying to search and find something not to pay as the policy is new and they are losing cash??? I understand their protocol but this is a clean and clear case we took out a policy for our gran paid it up to date and she suddenly died-now why are we getting the run around for a contractual agreement for our money??? Why is so less effort being made to resolve this matter as each time I call in for progress I'm told they still awaiting medical history from the hospitals and docs. Totally disgusted!!!
