Superfund withdrawal

My pervious company submitted a withdrawal notification on the 26 August, till today it is not finalized. Here is what happened on the 4th of November I started following up myself with Old Mutual and I promised that in 12 working days everything will be sorted guess what after those working days nothing happened and there was no commutation whatsoever and I called they told me they will apply for tax shortly I call after 3 days to find out the progress, I did call after 3 days guess what again nothing happened. I have been **** to so many times I guess they don't want to help me, with old mutual I have experienced the worse customer service.
