Lack of communication or not being able to get hold of the momentum funeral policy department

I’m very disappointed with Momentum. I have been trying to get hold of them since last week Thursday 11 January 2018 because I want to make a claim on the policy but their phone irrespective of the time of the day I make a call it’s say they are experiencing high call volumes. Tried calling Pretoria number but they still direct me to the same number/answering machine. I am really getting ****ed off because I need to make funeral arrangements which is supposed to take place this Friday 19 January 2018 but it’s being delayed due to Momentum’s lack of efficiency. I’ve sent several emails and they responded by asking for my policy number and that was the last I heard from Momentum. I am so flabbergasted and angry because they are quick to deduct the premiums but nowhere to be found when it’s time to claim
