Old Mutual Super Fund is the worst!!

I recently changed jobs and had to transfer my pension to my new employers pension fund. To my horror, it was the Old Mutual Super Fund ( I have had problems with the before with a previous employer). The money was paid to Old Mutual but has not reached my account since the 9th of September. I have been sent from pillar to post by the call centre agents and been told that I need to send proof that the money was transferred. This was already done by the previous pension fund on the 9th of September. I was copied on that email, so I know. On another call, the agent (Lundi), told me that he can't help me and that I need to send my query to yet another email address and I refused. Why couldn't he send through my complaint? He kept sighing on the call, almost as if I was wasting his time. I asked for his managers email address and the N+1 email address. He refused to give me the big boss email address and gave no reason why I couldn't have the email address. My pension fund has still not been allocated to my account. Int the meantime, I'm losing out on interest earned.

I'd like my money to be allocated urgently, including all of the interest gained while in was sitting wherever it was sitting. That interest is mine!!!
