Old Mutual not accepting responsability!

I took out a study policy for my youngest son in June 2013. I wanted a similar policy to my eldest son's that will pay out when he is 18 to assist with study expense. My (then) broker (which I trusted as my stepfather also had all his business with him) did the initial instructions wrong having me end up with a policy that will pay out only a third of the amount when he is 18, and 2/3'rds monthly. He basically took out an annuity instead of Max Investment. This detail I only found out in 2015 when I had the policies checked to see if I can change anything to make the return better. I asked if there is a way to have the money transferred or invested correctly, as it is his fault as he did not invest the way I wanted. I was advised that I can take out a new policy, which I did, and let the other one just go into a freeze period. Last year, 2019, I saw that the amount in the original policy is decreasing because of the yearly fees. I again raised a concern with Old Mutual but never really received a response. I tried the Ombudsman but also got turned down as apparently I took to long the raise a query. REALLY!!!!!?????? I just want the first policy's money to be added with the second and let my son's money grow until he is done with matric! I am losing here and it is not my fault!!! Please contact me to set this right!!! Old Mutual can surely do something in the name of client service when it is the client that is being wronged here!!!!!!!!! :( Then I received a call from another broker in October 2019, that promised me that he will sort this out for me. I was almost about to believe him (and my luck) as all of a sudden the did not keep his promises to get back to me. He let me know he had some personal issues, which we all have from time to time, but then it went quiet after he actually gave me his e-mail address too. The last contact he made was 8 November, being the e-mail address he gave me. Since then - NOTHING!!!!! I've sent him 4 whatsapps since then - 11 December, 17 December, 14 January and 30 January. He has not even read ONE of them yet. I even sent him an e-mail on 31 January 2020, which have also not yet been answered. So please, Old Mutual, try to regain my trust and contact me to sort this out. I am waiting in anticipation!!!!!!
