Worst customer service experience by FEDHEALTH

On the 16 January 2019 I submitted affidavit for my saving to be refunded with all relevant documents. I was told that the claim will me processed after 4 months. After months when I make a follow up I was told to submit the same documents submitted on 16 January 2019. on 28 May 2019 I did submit the same documents and was told the money will be paid in 4 days. On the 30 of May I receive an e-mail confirming that the money will be paid in my account on the 5 May 2019. Until now nothing was paid. I enquired with them this morning and I was told the money will be paid latest tomorrow the 6th of May, which is not guaranteed because I was told to contact them if I don't get the money. This is the worse service I have ever receive from Fedheath Medical Scheme after being with the Scheme for almost 12 years.
