Horrible service from momentum health

On 27 March 2022 I had an accident and had to go to the emergency room. Even though I have accidental cover on my momentum plan I had to pay everything cash. I did that and then had to do a refund claim with momentum its been 3 weeks since my claim was submitted. Everytime when I call I get a different story stating I will get my money that week. Now again I called and was stated I will only get it next week. I am now fed up with momentum not assisting me. I have no issues paying my monthly premium every month but now when I need their assistance in getting my money back there is so many stories and hold backs. Please all I am asking is for proper assistance and for my refund.
