Price changing

With a heavy heart I post this complaint , I have been a loyal customer of tekkie town for a few years now , because they always had good prices , lately there prices are the same as anywhere else not good anymore . End of last year I went into one of the branches and tried a pair of adidas running shoes on and the guy in the shop told me they are the last pair hence why they are so cheap R399 , I silly enough didn't buy them them anyway they were soon sold , today I went too woodmead branch only too find the same trainers but marked at a different price so when I asked the manager in the shop and I phoned head office they said they would work it out , 15 mins later they told me I'm lying and the shoes I must have tried were R199 and I argued and said no they were R399 .they told me I must have tried something else , making me out too be stupid , I'm very dissapointed . Anyway 9 of us from my running club will not buy there ever again , and I will convince my boxing club too do the same , they really are not the cheapest anymore and the stock is outdated
