No callback after a week

Last Wednesday, 4th of March there was an add in the Tygerburger for Ariel, 3 bottles for R99. I couldn't go that day because I was sick at home. I went the next day after work to Game and they didn't have one bottle left and they couldn't tell me when they were getting stock again. So I went to customer service to ask whether I can maybe get an IOU on the product, I was told yes, they can give me a callback. I went to the info desk to leave my details, I was told Reggie would get back to me. All I was asked for was my name and number and I was told I shouldn't put down the product I wanted a call back for. I questioned this, because the manager barely looked in my direction, before running off to attend to something els, so how would he remember what I wanted a call back for. I was also told that I CAN get a call back on that product. It has been a week and I find it hard to believe that Game has received no stock. What I DO believe though is that my name and number was just thrown away. I find this as very bad, unorganised service and I would appreciate someone keeping up their end of the bargain and giving me what I was told I can get.
