Worst service

Last week Thursday I mistakenly placed an order with Zando immediately sent them an email to cancel the order. I received an email in the morning that my order has been cancelled, few hours later I then received an email that my order was on the way. tried to call and their lines were not working still tried an hour later after holding the line for 15minutes line gets cut, called back again and spoke to Zuko Mndayi whom promised that he had logged the query and would receive a refund 3-5 working days. This all happened in Friday. On Monday morning I received an email that my order has been delivered but I recall cancelling the order. I called them again same morning same story happened hold for more than 10 minutes then get cut, I spoke to some woman who said the courier guys would be in contact with me to collect the item. They decided to come yesterday Wednesday with no sign of communication from both the courier guys and Zando. Today Thursday I call them to enquire about my refund hold for 10 minutes get cut call back again hold for 17 minutes only to be told that none of my queries have been looked into or logged. Now I have to wait 3-5 working days. This totally bad service!
