Pep online stole my money

I placed an order worth R571.90 of school uniform from December and when I call to ask about my order they telling me they can’t find it and that it is missing it’s been weeks calling and there is no resolution they are unbothered. I demand my money or deliver my school uniform, my parents are unemployed and old I am the only daughter I stay at res I worked hard for that money to ensure my sibling can get uniform, schools are about to open and they not worried about finding my order, I want my order or refund my money back! I want my money
