bad service

i went to the game store on Saturday regarding a HD decoder that was on promotion an employee took my details saying stock will be on Monday 13/07 I told him call me if it does not arrive, I go to the store Monday 13/07 @ 16.30pm to find no stock has arrived ! called branch Wednesday someone else took my details station they will call , no response I called again today one employee says there's stock and one says no stock !!! clearly no one @ the branch knows what they doing even the managers ! will never shop @ game @ mall @reds ever again!
