Bad service at Momentum Investo

I have not had joy with Momentum Investo where my retirement investment is since my retirement. The Financial Adviser is not helpful at all. The communication is very poor. The amount for airtime I spend due to holding the line when trying to phone is too much. I am in a desperate situation becausenI have my way I would like to invest my money elsewhere. I need help as to where there is a clause that I can nurse to withdraw my retirement funds and invest them elsewhere. Please assist.
