Terrible service from Momentum for old Metropolitan client

I was a client of Metropolitan for over 20 years (I have a number of retirement annuity policies with them). They were then taken over by Momentum and the service has been terrible! I am currently stuck overseas and have been trying to get information on my policies for months - I have emailed so many addresses and get no response apart from one email which sent me FICA documents. I filled them in, sent them back and have since heard nothing more. I am so frustrated - these policies are due in 2021 and I have no idea what is happening with them!
