Bad customer experience and refusal to reimburse a payment for a missing item

I was charged for a product I didn’t receive - R209, to be exact. Customer service is a joke - I was “assured that I want charged for missing items” - and they abruptly “resolved” the issue and ended the chat, despite the fact that I had proof of payment and the receipt that clearly shows I only received one item, but was charged for 2.

Get your s*** together.
