Momentum has not paid my approved claim

What a terrible service I have been receiving from Momentum, I have put in a claim for a medical refund since August till today I have not received my funds, the claim was approved and processed to their finance department on the 17th of September 2020, every time I call to follow up, I am told by the different agents that they are also confused why I have not received the funds as my claim has been long approved, I even wrote an email complaining about this, till today no response, well from here I am going to the ombudsman, Momentum is really disappointing, I am even going to cancel all of my products
