Worst customer service ever

I placed an Order with Zando on the 25th of July for a pair of shoes which I didnt receive as per their service delivery time frame of 3-5 working days. I sent them an email on Thursday advising them that I had not received my order and only got a response from them on SATURDAY. On Monday morning I received a call from the Durban office and spoke to a guy by the name of Rivesh Prenlall who had no empathy what so ever and all he was concerned about is whether should he cancel the order or what? *Rude*. I tried calling their customer service centre to do a follow up but had no luck in getting my call answered. Now they want to do a delivery after the time frame stated on the website and still expect me to have money after the fact!
