Worst ever service delivery from any medical aid

I am still waiting for response regarding various requests regarding benefits application with appsolutly no response or resolution. I even contacted the administrator of the medical aid but I haven’t even had a confirmation on receiving the email This is absolutely unacceptable to me that I can’t get a straight answer and quick resolution. I’ve been a member of Hosmed for about 10 years but I’ve never had this problem. I don’t know what to do anymore, even though I wrote that I’m going to report them to the business ombudsman. Still no reaction
