Bad Customer Service!!!!

Im writing this email with heavy disapointment as a customer ..today i passed at Spingo Boxer to but few items which included cheese of which i ended up not taking it anymore i then left it on the fridge that is closer to the tills..and paid for the rest of the items i took..By the time i was at exiting the store the security checked for my slip as they always do, -and he asked if i took Cheese the time i was shopping and i rep**** by saying Yes but i ended up leaving it behind, he said can i go inside the shop and show him where i left it and i did exactly that..he saw it where i left it and said i shouldnt be worried its because in this store cheese is the item that people '*****' more often soo that why they asked me to go back inside to the shop and point where i left it..I dont want to lie but this is humiliating because you end up looking like you stole something to other poeple,this disgusted me..is this how you treat your customers?? As *****s?? Im never setting my foot ever again to your Store!!! So just because there are people who *****s at your store now that supposed to mean everyone who enter at your store should be given the treatment i recieved?? This is sickening im Never setting my foot ever again at your store..we always buy from shoprites, checkers and other stores but never in my life have i been asked to go back inside the and point the item i left,if thats how you treat your customers then your service is Sickenin and stupid!!!
