Disappointed by Old Mutual service

I am so dissatisfied by your service at westgate mall. My investment is matured. I paid for 10 years . Now is time to claim , i was told the system is not showing the whole amount. I must claim manually and it will take time . Like really, i already made a budget for my money. Please improve your service. I thought i invested with a big and good company. I was wrong I am so disappointed
