Help option is bogus, there is no help

This is completely unacceptable, the order was literally canceled within minutes after we realised the order was delivering to my work address (which was closed) I find it very hard to believe that 6 burger meals were prepared within that time frame. The entire amount of approximately R800 was charged and when I wanted to dispute the charge, every email address and app contact info was no completely unhelpful. So basically, you can dispute but using invalid methods and it falls on deaf ears. Surely a cancellation fee is acceptable, but to deduct the entire amount is ridiculous.
