False advertising for the "free" medical screenings

Fedhealth offers Free Medical Screenings such as the Flu Vaccine and the HIV Finger ***** Test. I gave the Fedhealth Call Center to check which pharmacy I can go to, to make use of this. I was told I could go anywhere. I went to DisChem to make use of the service. After the test was done, I was told at Dischem, it could not go through on my medical aid and I would need to take it up with my medical aid. I called the Fedhealth Call Center numerous times including one with reference number 071220Q9FFGJ I was told they could not trace the call I made but they can advise that DisChem is on their panel but I would need to take the matter up with the pharmacy. Being shunted back and forth, I phoned Fedhealth and they said that the pharmacy is using the incorrect code. When I contact DisChem, they said that when they use the correct code, the code brings a co-payment four times the amount that I paid in cash?

This is so disappointing and such bad service because you pay so much for medical aid and when they falsely advertise free medical screenings, you as the member have to spend a fortune in phone calls and being passed back and forth between the service provider and the scheme. In the meantime, I have had to pay for the "free" service Fedhealth has offered.
