Client Misled

<p>I have been buying to this shop for couple of times. Last week Thursday I went during the 50% sale. I have 4 outfit in my hand when Im at the till the lady start saying no this pants are not on sale. Im surprised then I asked her then why do you have a 50% tag on it. Her response was they wer on sale during black friday....what is the date today?..She is saying they did not get the chance to remove the sale tag. So Im asking her does it mean every customer that comes to the store and pick up those pants you explain the same way as you are doing to me. My last question is was I not suppose to be given with the price I initially so ...then her response was the system is blocked for such.....This I regard as terrible service. Ive been in other stores and I know if its their mistake that actually give the customer at the price at face value...I was decieved by this so I decided to leave everything and go home. </p>
