Non existent customer service

Place and order on Friday, payed for next day delivery(Delivery today). Received the mail that my order has been shipped. Sent your "Customer Loyalty Team" an email at 09:02am and still no response (#***). Called your call centre 3 times, only to be put on hold and promised a called back, which never happened. When I called back again I was told my order would only be delivered tomorrow, and blame was put on Dawn Wing, no ownership taken by Zando, so what did I pay extra for!?? Will I be re-imbursed?!!
