Bad experience with claims Discovery Medical aid

I am utterly disgusted at your claims call centre agents. I have been calling since last week relating to a claim I sent in and nothing has been done as yet. I was admitted into hospital towards the end of Sept 21 and a Diagnostic radiology claim was paid twice both by myself and discovery. The supplier has since reversed the claim and I want to claim back the money from discovery this has been painful as they still claim to not have received any of my documents. I was rudely cut off by an agent called Aphiwe when I had asked if she could let me speak to someone who knows what it is they are doing. Come on Discovery not acceptable from a big company like yours. I was better off at Profmed!
