Ridiculous service and incorrect stock delivered

I placed an order *** on the 30th Dec 2015 for a set of JBL609C Split speaker system car speakers the Automated delivery date was the 1st Jan, Knowing full well that the 1st is a public holiday i expected delivery to happen on the Monday the 4th, i received an SMS confirming the delivery will happen on the 4th Jan before 5pm via Fedex, no delivery happened, i phoned and asked where the order is and they advised delivery would happen the 5th, and surprise the delivery didn't happen when i phoned for a further update i was told that they do not phone the third party only emails can be sent- delivery only happened on the 6th only to open the box and the incorrect speakers are in the box (JBL608C speakers delivered), now being furious as delivery took long and now need to go through the returns process only to be told that they cannot get the stock and will refund me and they sorry and when you express your frustration they say sorry they understand..they do NOT understand the frustration caused as i ordered it because i need it i didnt order them for it to be credited back to my account. I want the stock i ordered as it WAS available when placing the order or the SPEC equivalent
