Unsatisfied

Hi good day, I use pharmacy direct due to our medical aid, we forced to use them, from the time I can remember I've been having endless problems with them, when we call the customer care service we got to use our airtime and we still told to hold while they saying they checking but can hear them talking in the background, I've sent numerous of emails staying that if the medication is not covered by my medical aid not to take it out of my savings, but they still did that, and they give wrong doses of medication, I called them at the pharmacy and they not available so how do we get help, really unsatisfied
