Shoprite Evander 10c change CHEATS

I am new customer in Evander, but the teller service is cheating at its best. They don't give you correct change and say nothing. All of them are guilty, but if i am 10c change they will not entertain me. Please management, whats going on, u are aware what you employees are doing, cause its all of them, from liquor outlet to the grocery. I will switch and buy my grocery in Secunda. Its disgusting.
