Misleading us with red stickers

hi , i went to the mr price in kollonade last friday , i took a shirt . the original price of the shirt is R89.99 then you guys put a red sticker on it saying the original price was R109.99 now been reduced to R89.99 (which has been the original price all along) . on sunday i went to the mr price in wonderboom junction found the same thing . now tell us , why are you guys taking advantage of the fact that we buy items that have red stickers on and mislead us ? at least have the decency to remove the original price , do not be trwating us like illiterate idiots .
