Why lie to me?

I enquired about a product which I have purchased from Checkers before (Blattanex ****roach gel poison) and I was assured that Checkers does stock it but that I'd have to go to a Hyper store and I was assured that the Hyper in the Mayville Mall in Pretoria has stock. I went out of my way to go there only to find that they don't have the product. I could buy other ****roach poisons but NOT Blattanex which is manufactured by Bayer. I asked the consultant who works in that department and he assured me that they do NOT have that product on their shelves in that store. So what was the purpose of the exercise? Assuring me on Checker's social media page and a call from Cape Town head office that that specific product was available AT THAT STORE? Yes I could get other products but I need that product IN A GEL format which I have bought at the Checkers Blaauw Village in Pretoria North before. Why lie to me TWICE? So my time and petrol was wasted because of Checkers' lies.
