Fastway lost my delivery - no ownership

I purchased goods from Simply Shopping on the 10th September 2020 who then sent me a tracking number for Fastway Courier service. More than 3 weeks later and the tracking number still doesn’t appear on the Fastway website, I have no idea where my goods are, and no one is taking ownership to resolve the matter. Simply Shopping are “Simply Blaming” the courier stating they are impossible to get hold of. I don’t know if I have been ****med or not but this is not acceptable. Fastway must respond to the Simply Shopping claim that they have lost loads of deliveries or take ownership for the debacle. Any company that behaves like this does not deserve to remain in business, Fastway and Shipping Shopping alike.
