Online delivery: Late and items missing

Placed an online Order # ********** 59652 on 2017/10/11, with express delivery. Two of the 11 items were delivered 5 days later. I called the "call centre" and was told that the rest of the order is still on route. A week after the order was placed, another 7 items arrived. We tried calling the call centre on ***, but the staff is clueless, got through to an agent (Chante Hendriks) and she said I am at the "Canal store" said I dialed the wrong number! We are still two items short! My demands are simple: Deliver the full order and refund me the money that i paid for the "express delivery".
