Makro & Wumdrop still dropping the ball

I place an order on Makro in September the expected delivery dates were 01 and 02 October. Immediately on realizing that my delivery address had an error, I contacted Makro online and called the number, I have spoken now to several (more than 5 agents) including two agents from their courier Wumdrop. I have sent emails to Makro with my correct address and have deleted the wrong address on my profile. I have still to receive all my orders, including a recent order that has been sent back more than 3times by Wumdrop who confirm that they still do not have the right address. Today I have received part of a 12day late delivery, the Makro order on their system shows as delivered but I have queries even sitting on a call for 44min yesterday to have it dropped and then I still have to call them back to find out what the feedback is. I am extremely disappointed, and I just want my orders delivered.
