Worst online order experience from Makro

Ordered product via online store. Delivered incorrect product to incorrect person Send email, they contacted me and made promise to have resolved within week. Then they forced me to say it is a return and they dont know how long it will take to resolve Issue is that they should have something in place to check what they send. They should have reliable courier service that ensure to deliver to correct person and get pin from person and not make problem the customer's problem if they did everything wrong and now i get told that they cant tell me when or if i will get my correct order. What applies to me should apply to them
