Poor customer service from Takealot.com Undelivered goods

I recently ordered Carrol Boyes mugs set containing 4 mugs inside. The order was for 2 sets meaning 8 mugs. Only 4 were delivered. On the same day of the delivery, I notified them via email that only one set was delivered and not 2. Since then I have been calling takealot daily and speaking to various consultants, I've emailed them the bar codes on the 📦. Daily I call them to follow up, no feedback whatsoever. None of them acknowledge the emails I sent. I was told a supervisor will call me on Friday 8.13.2023. Still waiting. On 9.12.2023 I asked the collection centre in Canal Walk to assist, still no feedback up until now. Communication with takealot has been one way and I'm not even sure if they are attending to my query.
