Once Again....Game advertises and they dont have stock. My second bad experience and soon to be Last

Bought a cadac Cooker Top and a 3kg gas cylinder but they never had the cooker top however they said they would sell it to me and i can come through to collect the cooker top. Its now 10 days later and the branch at Game City (City View) still does not have stock, First how can you guys run promotions without stock and secondly how can you have extra cycliners and not enough cooker tops, You guys should have supp**** your stores with exact quantities of each. This is my second bad experience with Game in 2 weeks, First my fridge was delivered 3 days late and now this....What's going on? Please can someone from your Head Office contact me as i need to know what's going on in your stores.
