Wrong price for a product.

So on Black Friday there were a lot of specials and some shops had it for the weekend, my one was for the DSTV EXPLORA 2 it was advertised for R899. So on Saturday morning i called and was informed by Checkers Hyper Parklands that it is there is stock and the cost is R599 i asked again if it was for the dstv explora and she verified it that was between 8-9 am if you want to audit the call. I rushed there just to see that the explora was +-R1200. This false info is unacceptable. i wasted my time, fuel etc.
