Bad service of momentum on not wanting to pay out people’s retirement funds

I have made a claim on my retirement funds from momentum. I filled the forms along with my HR from my previous company I was working for, the form was signed by my HR and myself and submitted to momentum. We then received a feedback from momentum with all details of the process of claim and waiting period while the claim is being processed of 4 -6 weeks. My 5 weeks has lapsed last week with no feedback from momentum. I then called momentum wanting to find out why the claim has not yet being processed. Momentum they are not willing to help in any way. Then always telling me that they will ask the administrator why my claim has not yet being finalised since there’s no note on my claim as to why my claimed is not yet finalised. That’s same story they are giving me everyday when I call them. I then ask to escalate the matter to the manager and they told me managers are working from home and they can’t help me since they only depend on texting them. This whole process is so frustrating since no one is willing to help, right now I just feel that momentum they just do not want to pay out and they are just basically a ****. Everyday I call them with my money with no help. I will never ever trust momentum with anything and I will never recommend anyone to do anything with momentum.
