Old mutual funeral policy

I lost my mom on the 26 of November, it was unnatural so I requested post mortem and it was done on the 30th November and the doctor said he doesn't know the cause of death, so the death certificate was written under investigation, then on the 30th of November I submitted my funeral policy claim to oldmutual and they requested the declaration by police which I submitted on the 1st of December early in the morning, mind you I did submit all the necessary documents including the one from the funeral parlour and we were going to lay mom to rest on the 3rd of December, so they kept quiet until the funeral date passed and my close family member borrowed me their credit card to cover the costs until the old mutual policy pay, so I went back to the branch on a Monday 6th December to inquire about my claim since and all they did was to resubmit and that's when I got a message the following day Tuesday the 7th, they were requesting for post mortem report, so I went back to the giyani branch and they called headoffice and the guy I spoke to said they can't pay me without the post mortem results, and meanwhile they are still deducting my money while the is a claim hanging on, so how do I get to move on while I am being reminded by their monthly debits for someone who is no longer there, and this is just a funeral policy not a life cover so if they are confused on whether to pay double why not pay the money we agreed on when I took the policy and they will decide the rest after the post mortem results, because post mortem results/report take months even years, please help, to me old mutual is a **** and I will never recommend it to anyone.
