Appalling customer service at TFG online

This has to be the most unreliable, inefficient online group yet. I placed an online order containing 3 items with Sportscene on July 26th. 2 of my 3 items were delivered 5 days later. The item that made it to their Warehouse first (27th July) still nowhere to be found. It has been "At Warehouse" for 11 days in total with no movement Whatsoever. I have sent numerous emails to no response. I called in yesterday and was reassured by your agent Leonie that the matter would be escalated and will receive an email update by EOD. Over 24hours later, Nothing! This is as bad as service gets. Absolutely appalling!
