I dont know why I bother to go back there

I have had several bad experiences at the Food *****s Market in Umhlanga Pearls. Written to them and also on Hello Peter without even a call or response. Yesterday I went to do some shopping and of course several of the prices were not what was on display with discrepancies from 2 rand to 6 rand per kilo. I brought it the attention of the very unhelpful Indian manageress or supervisor and she promised me they would fix the issue. This morning I went back again and lo and behold nothing has been updated. Once again the sullen supervisor begrudgingly helps me and states "its only a couple of rand" but if you are *********** every customer by a couple of rand - it adds up. Why is that store not being managed from Head office as this is not the only issue ive had there
