Takealot of time and money

Placed an order on the 3rd of may 2019 (Order # ********** 2)The date given for shipping was for the 9th. On the 9th it hadn't been shipped, so I sent a query to them. Yusrie Allie responded and cancelled part of my order, a phone, without any arbitration nor any request from me. But ships the rest including a cover for said phone. Conveniently the phone is not at that price now. I as a consumer with rights, only see fit that they pay the difference and ship me what I ordered and fast.
