My Provident funds not allocated to my funds

I have been in contact with old mutual for the past few months trying to get my provident funds to reflect on my profile. Communications has been shared with me that they have received all relevant document from my previous employer but they amount still does not reflect on my profile. Every-time i call call them they hang up on me and do not want to explain where the money is as all documentation has been shared with them and they have acknowledged them and they have communicated to me that they have finalised the transaction.
