Very Bad Refund Service

I had an appointment on 14 March 2021, where they told me the form was wrongly filled and asked me to fill again and assured me i will be getting the refund of the previous one. Its been over 45 days now and i am trying to call and email continuously for an update but no response from them. Calls to the customer care always go unanswered, i am spending around 50-60 rands each day and i am stuck on hold and ultimately the call gets drop. Seeking urgent update on my refund status.
