Refund

I have made a payment for a consultation with Dr L Freislich of R500.00 in advance of the appointment as my medical aid ran out. On the 16th May 2019 I have send her the first email to cancel my appointment for the 23 July 2019 and refund me the R500.00 that I have paid in advance. I made 2 phone calls after the email of the 17th May 2019 to follow up on the refund. I was told by the nurse at the consulting rooms when I phoned that they will refund the money on the 29th May 2019. No refund was done and I have send another email on the 03 June 2019 and I still did not get a reply or a refund. I am in financial difficulty and I need that refund urgently.
