Complaint about Metropolitan Life

I would like to lay a complaint about Metropolitan Life. I made a payment of R20 000.00 in October 2021 which was my 13th cheque(bonus) that I had intentions of injecting it in one of my existing investments with therm which they had agreed that they do that. Unfortunately they have never done that and my money doesn’t appear in any of existing investments. I requested that they must refund me back my money since they have failed to inject my money in the already existing investment. That’s where the problem has started. I haven’t received my money till today I requested to them that I need my money back as from 19th of January 2022 till now as in 9th February 2022 haven’t got my money back. I have done all the administration and documents that were needed but still I haven’t got anything I really don’t know what’s really their problem because as far as I know I don’t owe them And they are the one’a who failed to fulfil the goal I wanted with them Please help Hellopeter for me to get back my money. Thank you!
