Bad Service from Online Customer Service Team

Ordered a bed from a 3rd party supplier through Makro. 1 of Makro's "online Only" items. the item was supposed to be delivered 2-5 days after the order was placed. 1.5 weeks after the order was placed I got notification from Makro's online team that the supplier is waiting for a delivery of stock. 2 days later I was notified that my order would be cancelled because the item was out of stock. Firsly, im frustrated with the supplier, how do they advertise an item for promotional sale on their own website as well as reseller's website at the same time if they know they have very limited stock available. Secondly, Makro's online team was not at all helpful when it came to providing feedback. They never bothered to send any updates on delays, I had to follow up with them myself and had to wait 2 days for a response. The responses were also so vague and quite useless.
