Late delivery/Refused Cancellation/No Refund

I bought items to the value of R1700 2 weeks ago. Their standard delivery is 3 days in cities. It took them 4 days. After I ad requested them to cancel my order when it was late after 4 phone calls to different people and 2 cancellation phone calls, They still delivered. I needed the items for a year end function. Anyway, I still could not use the items, the dress came with a mouldy stain....everything else was accessories to go with the dress and perfume and shoes... On Friday last week (30 November i requested to return these items as I ended up not using them as they were damaged and late. 3 days later, Im still waiting for these things top be collected and they will not refund me until the items are at their warehouse. I have been a customer of Zando's since 2014...this is the ****piest service I have ever received from them. Then each call I have to hold for 25 minutes...ridiculous service.
