old Mutual = No Answer

Good day,

Last week, I have asked that my pension fund been made paid up, first we had a problem with the policy number, however when we sorted that out it was confirmed by Old Mutual that it has been made paid up. Thereafter Old Mutual asked me for a proof of banking details for a refund, I gave them my account number as well as my most recent bank statement. Until today they will confirm that they have received it, they will confirmed that the bank statement that I have supp**** is sufficient. I send numerous emails, no answer. secondly I asked them what the refund is for, no answer.
