Discovery Health delayed time to pay MSA back

I ended my membership with Discovery Health end of June 2022. I have a substantial amount of money in my MSA. I called the Call Centre and spoke with an agent that promised that they held onto it for 3 months and I would receive my money mid October because it would take 15 days to be released. Please note that I do not gain interest on this money - Discovery earn the interest on the money. Mid-October and Mid-November have now come and gone and there is no sign of it in my account nor any communication from Discovery Health. Today I called Discovery Call Centre (I was on the call for 25 minutes) and the lady asked if I had requested the money previously and if I had a reference number. My question to her was why do I have to request my money from them? She says it is due to be paid out to me mid-December. This is now five and half months to get my money back to me. Their excuse is that they have to protect themselves. How are they protecting themselves? They are gaining interest from my money. This seems greatly unfair. ***
