AWFUL SERVICE FROM DISCOVERY!

On the 1st February I was wrongly charged for a phone consult at my GP- it was a phone call telling her that the medication she prescribed to me on the 28 Jan was not working. I got a notification on 8 Feb that I was charged. I took it up with the doctor's rooms as this was unacceptable. I got an email from the doctor's rooms that they emailed Discovery to have this amount reversed but to date- 24 FEBRUARY- 2 WEEKS LATER- NO RESPONSE FROM DISCOVERY. No emails, no feedback, no question and NO REVERSAL!!! WHAT AWFUL SERVICE AND VERY SHOCKING THAT NO ONE HAS SAID ANYTHING!!! WHAT IS GOING ON- RESOLVE THIS!!!!
