The three year of struggle of being oldmutual client

Thank you for the opportunity,In 2014 my husband was working in a certain company as an outsource casual but they had a provident fund called a Superfund from Oldmutual in until 2017.In 2018 they were employed permanantly by the same company but they were not allowed to claim in the provident from the previous company they its because they were still employed,2019 he lost his job they paid what he thought was due to him however I noticed that the money paid to him was way to little I investigated and found that when they were registered as permanents Oldmutual opened a new provident fund despite having an existing fund so the 1 fund was not claimed for.November I initiated the claim sent relivant documentation but with no luck I continued 2020 they will send paperwork he signs and I send then they keep quiet aftet a month I will phoned they told me that my husband was still under payroll from the workforce grouo of which he wasn't I called the workforce group they confirmed that he was not on payroll since 2017 and they sent me an email and screenshot as proof that he was not I took all the information forwarded to Oldmutual then they sent me documentation for him to sign he did and we were suppose to wait 21 days then they was no payment I called them they are told me he was still on from workforce. Until this year they are telling me the same story ,I asked one of thier call centre agents why they wait for me to call them if the is an issue with the claim "she said its not Oldmutual duty to call me I am the one who should call them instead know its been 3years callingand emailing them no one wants to assist me I spent more than the claim .I have sent an email to them two weeks ago they still not rep****. I hope Hellopeter can assist me regarding this matter.
