Metropolitan Life - Dissatisfied with services

I am very disappointed with the services of Metropolitan Life Soneike branch in Kuilsriver Cape Town.

I request a withdrawal of 1/3 of three pot savings on my retirement plan. They told me that I need to come to the branch to fill in forms because my banking details do not correspond. Upon signing the forms, I saw that the forms do not speak of withdrawal of 1/3 three pot savings but the forms speak of full withdrawal of my retirement fund which was not the instruction. On top of that I am not working and I am charged 40% tax on the full retirement fund. The Metropolitan Life branch manager said she will investigate and come back to me but nothing. I am writing to express my dissatisfaction with the services. Metropolitan Life has placed me in an unfavorable financial position.
