Momentum health service is pathetic

Momentum health decided to change our Health Saver cards as of 1 April 2024, to date I still haven't received my card all though I pay a huge amount into it every month, after I complained the cards manager Marry-ann Buffet called me and she assured me that I would have my card latest 14 April 2024. I have since emailed her and phone her and she hasn't gotten back to me. She doesn't answer her phone and she doesn't reply to messages that I left or my emails.
