Pathetic Online Service - Makro

I've ordered an inflatable bed on the 14th July online, and the delivery date was supposed to be 21 July, according to Makro - An item arrived on the 28th of July, which was the wrong item from what I ordered --so now Makro just do nothing -- I've phoned 3 times to let the Call Centre know -- I've given the Order number ---i have to go onto the makro website with my profile --- but it NOW shows no orders or past orders --- NO ALL OF A SUDDEN I NEED TO RESOLVE THIS PROBLEM -- instead MAKRO should do a PROPER QA before they ship the Item to the customer --- im STIL NOT SORTED --sort it out !!!!
