Unsatisfactory sandwich wrap and rude non apology

Wanted to share my experience with Caltex ravensview table view freshstop.On the 18 th November I purchased a wrap that indicated it was a "ham and cheese"wrap ,on returning to home only to discover no hamin this wrap .Later I took my uneaten portion of the wrap back to freshestop, only to encounter a very disserving unpleasant supervisor by the name of Ester who didn't literally say two words and proceeded to refund me without any apology, and further more after me correcting her on this started to berate me. I have followed up with management with an email on my dissatisfaction on the whole matter and was responded to that an investigation on cctv camera s would be looked into? My feelings on this matter is that the person who served me will more than likely continue her bad service traits and there will be no consequences,as the response letter didn't actually say anything relating to Ester and her bad performance in dealing with the matter of a simple apology. Sad when South African s get so numb to accepting non service,bad service,rude service, uncaring service and sorry, thankyou is not a feature in communication.
