Disgusting service

My husband has an annuity with momentum that was supposed to pay out on 1 December 2018. In October we drove to the centurion offices to get the ball rolling but nothing has happened. We phoned the offices in the first week of December to find out what was going on with the response that it was at SARS and would take 2-4 days then we would receive payment by the 14th December when we phoned on the 13th December to find out if payment was going to be made we were told it hadn't gone to SARS yet so what happened since the 1st December and why is it such a mission to get paid out when they knew since October that the policy had to pay out. I have never received such poor service in my life where you get fed a conference story every time you phone or do I have to go back to centurion and cause a scene and trash momentum on every social media sites
