Worst online experience

Makro Online - Worst online shopping experience ever! Disappointing service! Purchase product, after inquiring when delivery would be made informed courier had not collected. The following day told the same, courier not collected. Next day received a call stating item is out of stock, followed by another call a day later stating issue with incorrect item app**** to product. A refund was requested which was received a week later but the delivery charge of R 70 had been deducted. Surely this is *******?? Oddly enough a few day ago I an add popped up showing the item purchased at the same price.
