Still no feedback on missing item on my order from January

I am completely frustrated and have nowhere else to turn. My emails that I send to customer bounce back meaning that my email has been blocked by Makro customer care, they can send me but if I respond it bounces back and it's been like this since last year.

I placed an order on January 15th 2025 MAK***. The order was delivered on January 17th, immediately I noticed a missing item a campmaster tripod chair and I contacted the call center and whatsapp line. Ref ***. Till now I haven't received my missing item and I don't get feedback up until I make contact. The customer care puts me on hold to tell me I will receive feedback no feedback from Wonderboom or customer care Makro. I call again to be told it was supposed to be delivered and I said I haven't received anything not e even a call or message to say I should expect delivery in a particular date. When I called last week they said they will contact me. The only contact I got was an email saying it was escalated to the relevant department. Till now February 5th NOTHING. Why has this been escalated twice? No answers from makro very disappointing as this is the first time this happened since order for years and now no help or communication. If I call the Wonderboom Makro they direct me to customer care. Customer care for 3 weeks has been escalating the matter with no feedback.
