Momentum - Worst Customer Service I Have Ever Encountered!!!!

In the span of the last week I had requested certain pertinent information in respect of my RA. What I received back was an unprofessional excel s/sheet that Momentum should have been ashamed to send. I then sent two follow up emails last week requesting for the 2nd time on how to go about cancelling contributions to my RA as I no longer want to do business with Momentum, and a breakdown of my service fees. To date, I have not received a response on either email. I have spent a large chunk of airtime on sitting on hold or having to phone back. This is really disgusting beyond belief and considering how efficient you are at taking my money, one would expect that efficiency would extend to the rest of your service model - Apparently not. Someone from Momentum must get in touch with me ASAP to find a resolution on this!
