Shocking service and No delivery of product

On the 18th of March 2015,I purchased a bed from the Woodmead Rochester Furniture.I arranged for delivery of the bed to take place on the 28th of March 2015 at a certain address in Kyalami.On the 25th of March 2015, I went into the Woodmead Branch and spoke to the sales person (Lloyd Sibanda)who sold me the bed to advise him that due to unforeseen circumstances,I would not be at the address specified for delivery.He agreed to put the delivery on hold and keep the bed in storage for a month until I advised him of a new address.On the 1st of May 2015,I again attended at the branch in Woodmead to advise Lloyd of an address at which the bed can now be delivered to.He told me that the bed had already been delivered to the address.<br> The store now refuses to take responsibility for the fact that I paid for a bed that I did not receive. 21 days have passed and my complaint still has not been resolved or attended to.
