Extremely worried about AF as my fund administrators

Receive and email indicating that 'ongoing contributions have been switched in accordance with the provisions of the lifestage model applicable to your retirement fund'. Lof on to AF Connect. Realise they have by retirement age wrong. Request to be contacted. Four weeks and no contact. Try WhatApp number - no live operators. Phone the call centre. Hold the line for 7 minutes. Explain situation to operator, who transfers me to the appropriate section. Get a recording that I can't be assisted as staff have training and the call is ended abruptly.
