Pathetic service for online order

I placed an online order on 18 June 2020. I received notification that the order was fulfilled at Nicolway branch on 19 June 2020. To date the order has not been delivered. I contacted Dischem who could not tell me where exactly my order was and would get back to me on the morning of 24 June 2020. Nobody has called me back. I have sent an email and sent a direct message on twitter with no responses at all. The courier company Pulse does not come up on any courier list so I cannot track the parcel myself. I have important Vitamins and essentials that I need and nobody at Dischem to take accountability to find my order and get it delivered. It has been almost a week since the parcel left the Nicolway branch how are these medicines being stored and how many people have handled it since. Why are you using fly by night couriers who cannot be traced ? How is it that a manager that called me does not know what courier company Dischem uses. If my order is not delivered by end of business today I would like it cancelled and my money refunded.
