OLD MUTUAL MUST STOP ONLINE TAX FREE PLANS APPLICATIONS

I opened tax free savings plan in 2021 online for my 14 year-old son. They have deducted money with no issues. I went to Phalaborwa branch to disinvest and I was told to come with my son, and his bank statement. On the 5th of September 2022 i went again to Phalaborwa branch with my son this time to disinvest and they sent me back again to come with the listed beneficiary who happens to be my wife (his mom). On the 12th September 2022 I went with both son and his mom as requested, still I did not get any help. I was told to produce contract number and I don't know it by heart. The most confusing part is that every time I go there, my case is heard by different person and when they phone someone, they still can't help me. I am tired of their excuses. I went there THREE times for one thing. Old Mutual should stop online applications because all the people I have interacted with, they said it was the first time they seen such.
