Very Unhappy - Misinformed

The Personal Health Pathways is not working properly. They sent me for a mammogram and the flu vax at the same time. They didn't do research. It cannot be done together. I went for the fax first and a few days later I went for the mammogram. The mammogram showed swollen lymph under my arm. The Dr said it is most probably due to the vax. It was noted in the report as such. I had to go back 3 months later for a check up sonar, which was also fine even though I had to travel 80km to a preferred supplier again. All was normal. Then the BUMMER. Discovery refused to pay for the follow up sonar! They paid it from my medical savings account! And this was no fault of mine. I'm not the medical expert here, they sent me for the two things at the same time. No I have to pay for it. So due to their error I had to pay R1 614.70. I took this up with Discovery and they requested I send them the proof (scan reports). I sent them both reports, the first and second visit, which clearly states it was due to the flu vax and they still refused to refund this amount to my savings account. i have always been a loyal supporter of Discovery Health for many years. But his is terrible. How can a medical aid not know this and then refuse to pay for their mistake?? Make the client pay???
