No delivery of online buying... why have the option

I have placed an order on cyber monday the 2nd of december... to date I have received no order.. I received a message on friday that my order is out for deliveries and will be arriving at 1700pm that day.. and nothing came.. I have made numerous calls to the call centre and escalations daily.. absolutely nobody gets back to me no resolution. This is the worst online service I have received in my life.. if Edgar's has a backlog due to high demands they should have foreseen this as an experienced business. delivery is 2 to 5 days.. I am 7 days with nobody telling me where my parcel is... call centre uses same tracking service that is available online they can't even advice who is the courier company responsible... how are you supppse to provide customer service for something your'll are clueless on.. I want someone to call me and give me exact date as to when my order will be delivered.. keep to your promise Edgar's.. dont set standards for face value and the proof in the pudding is u are unable to deliver...
