Old Mutual keeps passing the buck

I made a claim on my investment on 04 June 2018 and the money was supposed to be paid in 15 days. On the 27 June 2018 I called to follow up on payment but there was no response. On 04 July 2018 I was told the money will be paid in 2 days and a person called Monica will call me but she never did. On 12 July 2018 I visited the Kroonstad Client Services Branch to find out why there was no payment. The branch manager called the head office to find out why there was no payment he was asked by the person at the head office why I did not remind them about my claim. The branch manager called me on 18 July 2018 to find out if I received the money and when I told him I did not he connected me to the head office. The person I spoke to told me that the claim was rejected abut could not tell me why. According to my investment the turnaround time for receiving money is 15 days but all i have been getting from Old Mutual is being sent from pillar to post and different stories. All I want is my Money that I invested because I'm not asking Old Mutual to give me a loan.
