A month & a half and still no refund

On the 27/04 I placed an online order for the amount of R401.70. 06/05 - order cancelled stating items can only be bought in store and that refund of money will take place within 3 to 5 days. 13/05 - emailed as no refund had been received 15/05 - called and emailed as I received an email stating my cancelled order is now out for delivery. It was advised that they could see the order was cancelled on the system and they are contacting the store and I will be called back. NO CALL BACK RECEIVED. 18/05 - email received stating I would have my refund in 3 to 5 days. 21/05 - received a part refund of R74.90 25/05 - emailed as the rest of the refund has not been received 03/06 - called in spoke to Sinehlanhla (ticket number 799781) was promised a call back by a manger. NO CALL BACK RECEIVED. 12/06 - called in again. Was on hold for 30 mins.... 30 mins of straight hold music because there was apparently only 1 manager in the whole call centre and this person was on lunch. And the best thing of all I still have not received my refund.

All I want is my refund. Why is that so hard. Makro cancelled the order, not me! They decided that my order was not worth delivery, therefore I should be refunded my full order amount.
