Mr Price has poor customer service!

I placed an online order on the 24th July and it was delivered a week later. When I checked the content I discovered that there was a missing item, the next day I contacted them via their WhatsApp customer support platform and was told an investigation would be logged to the warehouse and feedback provided. It’s been two weeks, no feedback! I emailed them same silent treatment. I want answers and will not settle for such disgusting customer service! From where I’m from this is called *****ing!
