Oldmutual Drama to clients

I am a foreign national with temporary permit. I resigned from work last year and my pension was transfered to oldmutual. My financial made to signed to put my into an investment portfolio with oldmutual saying SA law will only allow me take my money after I am 55yrs. Now I have sent series of email to them the oldmutual that i want my money but the said the only way i can take my money is to go through emigration process. The emigration is done through Reserve bank and one must start the process from his or her bank. I went to my bank only to be told that how can immigrant goes through emigration process. I went back to oldmutual and they told me I should get visa exit which never exist in home affairs. I have even gone to home affairs and Home Affairs doesnt have control over when i must leave the country or come in the country or I must report to them am leaving the country. The emigration process is for South Africans not temporary permit holders. This covid19 I have never recieved any social intervention from the government. I am not working oldmutual should give me my hard earned money they said I must be here till 55yrs or bring documents which is never exist for temporary permit holders. I am loosing my house because I have not paid my bond. I am loosing my car and living hungry here but I have over half a million with oldmutual. Must live till 55yrs with which permit? Oldmutual doesnt seems care so my fellow immigrant becareful. My next action to hit other media platform.
