Poor customer service

My pension fund was supposed to be transferred from the Transnet Retirement fund to the Momentum Funds at work scheme. The transfer was done incorrectly and as a result my pension fund is now sitting in a wealth preservation fund instead. I have been trying to resolve this for over a month now but to no avail. No one will answer my calls or return my emails. Everyone is either in a meeting or not available. Absolutely shocking service from Momentum. If i was to just leave this unresolved I am absolutely certain that momentum would do nothing about this. All the emails I send get an automated reply. What is the point of sending emails if nobody replies? If there was a zero star rating i would most certainly give Momentum a zero. Not feeling too confident about leaving my pension in their hands. Disgusting!
