Deceased pension fund claim

My husband passed on 19 February 2024, pension fund claim has been submitted to Momentum but there is a big delay that is costing me as there are a lot of needs to be met from the funds that are not being released. Worse part is when I send emails, no one responds, there is a CINPF email that I send emails to, that is suppose to respond within 48 hours as per their auto reply, but until today, no reply. I only get feedback when I call, and the feedback is clearly that we are sitting and waiting for a respond from the employer. If he doesn't respond, we will sit and do nothing until he does. Please assist on this matter.
