Game online - Extremely bad service not acceptable at all,

i bought an item at game online on the 14th of July and and 2days later i got an email that my order is dispatched, on the 4th day i called and i was told that my order is at a warehouse with the delivery company and i should wait they will deliver before day 14 as promised, i called again before day 14 and requested the name of the company that is dealing with my order and they gave me but the company said they don't have my order. when i called to tell them they said there's an error on the system they are currently fixing it, till today 3 days before a full month i have not received my order, every time i call i get the same message head office is currently working on it.
