Poor service and *********** staff

Terrible Experience with this online store. Purchased my sneakers on the 05/01/2022, and got a waybill on the 06/01/2022 from the courier company. Tried to track my order on the courier website but no info available on the parcel. After waiting 5 working days and still not receiving my order I called the contact number on the website. Lady who answered took my order number and promised to enquire with the couriers as to where my parcel is. Never once updated me on my order. Called the store again on the 17/01/2022, this time a gentleman answered and asked me to whatsapp my order number which I did. Received a parcel on the 18/01/2022, but it was the wrong sneaker and not what I ordered. Phoned the store again to say that I received the wrong order and its not what I paid for. Lady told me to call on whats app which i did but my call kept getting declined. Phoned on normal cellphone number and lady answered saying she declined my call cos she is busy. Why then ask to me to call on whatsapp? Got irritated and had bit of rant saying they should call me when they ready to resolve the isssue. Issue not resolved and my calls are still been unanswered and no response from them.
