Bad service

I visited game store at Mall@Reds this morning . I wanted to buy Defy air con 12000BTU indoor and outdoor . When i arrived there i was assisted by Modise Motlana who told me that they have plenty of those air con . I told him i will come for the airconditioner after the church service . I even asked him if he was sure that they have air conditioner which he definitely acknowledged that . Coming back from church i waited for an hour to be assisted . I even requested the store manager to be called which i am still waiting for him . I didn't get the air con as the store was left with 2 outdoor and 1 indoor . This wasted my time , my petrol . I end up going to buy an aircon at Pick and Pay at a high price . I want Game to get those aircon for me if they can i want compensation regarding the money that i bought from Pick and Pay .
