Returned items , 6 months later no refund

The purchase was done on the 20th August 2015 for my Mom a cancer patient<br> I bought two bottles of Selvestrol at R800.00 each which was a discounted price. As per Sarah the normal price is R900.00 per bottle .On the day I did a blood sample test as well at R450 .. total paid . receipt R2050.<br> <br> A week later my mum passed away.<br> I returned the two bottles for a refund ( unopened and in the same condition given to me) <br> Sarah the lady that sold it to me, indicated that she cannot refund me. That she would sell them for me if I left them with her & that she would call me once she sold them. Due to my emotional state over the loss of my mum and not wanting to be drawn into further argument, I didn't protest & left the items with her. This was in November 2015<br> <br> I called Sarah every two or three weeks thereafter for feedback & all I got was I haven't sold them yet .<br> It is now five months & I called her once again indicating my right to my refund as per the consumer protection Act .I would like my refund failing which I would take further action.<br> <br> Sarah was rude , shouted back at me that she will speak to the supplier & come back to me . Its been 2 weeks & nothing yet
