dont wanna give my money back

On Friday 20/03/2015 I wanted to pay a bill of R7750 then the limit exceeded and only R5000 went through then the withdrawal limit is R1500 so I wanted to pay R1250 then pay the other R1500 the next day.. so I went to the food court and realised I only had a R150 instead of R250 in less than 5 minutes I realised my mistake.. then the supervisor did a spot check but the cashier was over R300 short so they could not give my R100 then I went to information and explained my situation to 4 different managers.. when the supervisor tells a manager the cashier was R200 short cause they found R150 at a till under a paper where the cashier relieved.. and i was told they going to check camera's and I need to go back Saturday to speak to the big boss.. I then phoned on sat and was told it's a public holiday and the next day was Sunday but they will phone me before 10am today but I asked then to phone at 3pm cause in can't talk on my phone at work and in still waiting. I'm now sitting at home without bread or anything to eat as that R100 was to last me till payday:'( and I also told them I can't wait any longer as I need to walk home it's getting dark they shoot in the area. Left after 8pm!!!
