No delivery and poor service

Purchased 3 items at Edgars online and they were not delivered. I received an sms on January 30, stating that my goods were not going to be delivered because the courier was hijacked. Subsequently I called the customer service line and they assured me that a new delivery would be made and that it might take a few days. Did not have any news from them, so I checked the website. There it stated that the order was delivered last Thursday (01/02). Called again 05/02, at 13h01 and registered a complaint under the number Ref. ********** 2784/GO saying that I did not receive anything, The attendant assured me somebody would call and explain why it says that the delivery was made at the website, when it obviously was not. Still waiting for a response of any kind. Very disappointed.
