Makro App Delivery-Service Failure

So I ordered quite a few Items from Makro app 2 weeks ago, some items arrived and some not. I'm extremely dissatisfied with the customer service and poor process on Makro side. Its taken me about 15 calls every day and 4 delivery guys rerouting the package back & forth and nobody is taking any initiative to resolve or get the order delivered. I'm at a point where I really don't know what else to do. I hope that the correct Makro team could see this, in order to address the process failure. Surely they must be loosing a lot of clients, due to this kind of service offered. Customers please do not use the Makro App.
