Vodafone doesn't correct router delivery address and DHL doesn't allow changing delivery address

[CDEM]

Hello,
I need urgent help.

Here is the background:

1. I mistakenly put the wrong packstation code to the router delivery address
2. DHL returned the router to Vodafone
3. I contacted Vodafone to change my delivery address. They said it wasn't necessary because I can change the packstation code on DHL website (see attachment Vodafone1)
4. Vodafone shipped the router for a second time.
5. I contacted DHL to change the packstation code because it wasn't possible to change it on their website. DHL told me packstation code can't be changed (see attachment DHL)
6. I've contacted Vodafone again. They are saying I should contact DHL. I've told that I already have but they don't listen.

What should I do now?

Thanks

The customer service employee I spoke on Dec 23rd told me that he/she corrected the delivery address for the third shipment. I wanted to double check that so I've just contacted the customer service. Turns out, it wasn't corrected and hopefully now it has been corrected. I'll see.
