Not to be trusted

Wanted to place an order a week ago and was told stock needs to be packed and that we should place order for this week, pay before Monday at twelve and delivery will take place on Wednesday. Well no delivery transpired, tried numerous times during the day to enquire but to no avail, line gets cut, the one time I got through the sales rep, Sipho, apparently couldn't hear. Then phone back again just to get told that Sipho is not at his desk, the lady then offered to find out from warehouse management why the delivery wasn't made, and that she will get back to me. At 16:45 I phoned again just to be greeted by an answering service telling that they closed at 16:30. Full payment was made for goods and delivery, just totally unacceptable!!!!!!
