Bad customer service

My name is Lindiwe Sifundza i work at Woolworths also at Elridge Square, Friday on the 26th of April during my lunch time i went to De*****s steers to buy food for my family i then asked them to hold the food for me will collect at 18:45 because I'm knocking off at 19h00. I forgot to collect my food due to the busyness at work and we were short staffed so when knocking off i forgot about the food, the next day i went there to explain n give them the slip to my surprise they went n took that same order from yesterday told me it was stored in a fridge. I asked for a refund since i couldn't eat yesterday's food. They called a manager on duty which the guy came n told me they cannot refund me my money back it's either i take the food and leave because the money i will not get back n i will not get fresh food as i requested for fresh food as the second option the guy refused and told what do i expect them to do with that order from yesterday. I explained to him that the burger there is lettuce inside and tomato how does he think those are by now he told me is my fault I'm the one who didn't ferch the food so it is not their problem. I asked for someone senior than him he told he is the only manager there unless i want to speak to the owner of the company i said i don't mind doing that he told me the owner is on holiday, by that time he is busy talking to me the staff is gathered n laughing saying who the heck do i think i am. I saw the situation there n just walk out n left i left the food n my money so please i want my money back n to be compeseted for the humiliation i went through. I won't eat yesterdays food never, I will never buy from steers again n every one that knows me will never buy there ever. I used to always buy their sharing meals for my family but never again. I acknowledge my mistake for not collecting the food but I'm a customer. I believe customers should be put 1st. Please assist me with this matter. My money back Please
