Pathetic service for couriers

I placed an order on SHEIN and delivery was assigned to Fastway couriers. On all calls made to their customer service the calls were silent and then the line cut. I alled backe numerous times as I did not want my order to be cancelled. I emailed no response received. Still no delivery of my order. I received emails from SHEIN stating Fastway couriers attempted delivery or they tried to contact me, which is a lie, Fastway send false incorrect milestones updates.
