MOMENTUM- no end in sight

I started a critical illness claim for coronary artery disease on 10 July 2018. I have been allocated a kind consultant addressed to my case by the name of 'Peter" (other info private). While he is according to him trying his best to get this claim finalised - Momentum is a back and forth battle of every few weeks wanting more and more forms filled in. The stack of claim forms and all supporting documentation handed to them on 10 and 11 July. Then you wait a month nothing- call- told you need to complete more forms- Wait another month told they need more forms and 8 years if medical records. Why can a list of what they want be confirmed at the time in July 2018. Now 16/11/2018 and still no answer from assesor as what next they will require. Besides from having one of the top cardiologists in Cape Town looking after me and a class A Doctor (GP) ....i still am not 1 step nearer to the end of the road. I am treated as if I am trying to ***** from the welfare here. When i took out the policy i was assured of the best service and most realiable when it came to cover. Never in my wildest dreams did I expect to get so ill at such a young age. I am disillusioned, disappointed and just fed up with the lack of service from Momentum While my consultant assigned to me -quote his words" is doing everything within his power"- I suppose only handles paperwork and presentation..........but only after i hound them and follow up. IF I dont call or email- nothing moves along. So 17 weeks down the line no progress. What do i do?
