Disgusting and poor service

I have ordered two item online on the Zando website, i then recieved an email to state my delivery had been upgraded to express and i will recieve it in the next two days, which would have been yesterday 01/08/2018, i only recieved one item from this order. I queried it at 08am this morning and was told that they will revert with feedback vis email or phone call. i am still awaiting feedback 6hrs later, when i called again they said they have not recieved any feedback from the courier i then asked can they not call to get a faster response from the courier and the guy said no. This is such poor service and ridiculous, when i placed the order i did ensure that i ordered it earlier to get to me on time. I need this item delivered to me tomorrow!
