Old Mutual

I write to you with lots of disappointment, I left work on the 5th of February 2020 and Old Mutual were handling the company's provident fund that I worked for, I got the payment last year July, now I submitted my tax returns for year 2020 SARS has declined the application saying Old Mutual needs cancel the IRP5 for the year 2020 because according to SARS it looks like I got the payment twice for 2020 and 2021 and there is no directive on the system, I did raise this with Old mutual the response I got was they can't fix it and SARS cannot do anything with my application, I have a refund that is due to me I cannot access because of the pending case that needs to be fixed by Old mutual it's been 4 weeks now without any help, as someone who is studying I need to pay fees for the varsity I'm really struggling, i hope i can be assisted
