Awaiting refund and struggling to return unwanted items

I've ordered from other online clothing shops before but received the worst service from Zando so far. I placed my order ********** 79 on 28 October of R3454.00. Two of the 6 items were delivered 31 October. On 24 November I emailed customer care asking where the rest of my items are? I haven't received any emails or phone calls explaining why the rest of the order is taking so long. I asked for them to return my money as some of the items were suddenly out of stock and then cancelled without Zando returning my money. Received email from Fazlin on 25 November saying they will follow it up. Emailed them 30 November when I haven't heard from anyone yet. Received an email on 30 Nov: "Thank you for your email. We are terribly sorry for the inconvenience caused. It seems as though there was a system glitch with the Forever New items in your order. I am currently following up as to why there is such a delay with having these items delivered to you and why you were not notified that the items are out of stock. Please confirm if you would still like to receive these items or if I should cancel and refund you." 4 Dec I emailed them again. 5 Dec received email the order has been cancelled. Meanwhile 2 items were delivered but the fit was wrong. Emailed them but still waiting for reply. Meanwhile received email on 5 Dec saying that refund will be processed and will reflect in a few days. Will have to wait and see whether that happens. Will not recommend ordering from Zando.
