Zero customer service

Just the other day I wrote a complements for Makro wonderboom service Now I just received a bad service again, I placed an order where I got a notification that two of the items are out of stock. Now when I receive the order again two of my stuff are missing. Their WhatsApp communique is useless they keep on referring you fron one consultant to the other.

I am still waiting for the matter that was escalated yesterday early in the morning, on the App it shows that the items are ordered and approved, however where are they????????????????, no notification of items out of stock or maybe I will get a refund.

What criteria exactly are you using to hire your customer service consultant, your service it can go from hero to zero within the blink of an eye.
