Old Mutual-I am paying for your mistake

Lost my job due to Covid and before I left I submitted documents to say that I want Old Mutual to keep my provident fund paid-up and active. I have been without work for 1 year so far and am desperate for a tax refund. My tax return on e-filing was rejected because Old Mutual did not submit a directive to SARS stating that I DID NOT cash in my provident fund. For 11 days now I have been bounced from pillar to post on OM client support and getting ZERO help. I have phoned multiple times and hung on ad-nauseum using all my airtime and all my patience, only to never have a single call answered. ALl I want is for OM to submit the tax directive to SARS as they should have done 1 year ago so I can submit my return.
