ZANDO is really messing up now

My order was placed on 05 December. Due to system being busy that day, incorrect address was chosen. I notified the contact center immediately and they told me I must wait for the sms deliver first to change the address. I did that and till today haven’t received the order , AFTER I did numerous follow up calls to find out where my order was. When the order was dispatched, it went to the wrong address, that I confirmed twice with them to change. Apparently my order was sent to builders warehouse which is not my requested address . I need someone to tell me when I will get the parcel or I get a refund
