Timeline prolonged

I have been working for a certain company that our pension funds are administered by OD, always when i call the OD call centre the pay out time for my pension payout fund is pro longed, I had the same problem before in 2015 where it took them 3 months to payout to me without no valid reason,even now i don't know whats the reason of them holding back because all the supporting docs have been sent through, at first i was told it takes 20 days for a pension fund to be payed out , I received an sms on Monday that they have sent my claim to SARS, today i called again just to find out how far is my claim and I was told that i will have to wait for another 5 days..I find it ridiculous
