did you get any emails from check24 or other firms that your order is in work ???
if not, order directly from Unitymedia Homepage. You got special prices for online order.
Yes, check24 sent me a letter that order sent to Unitymedia and then I called Unitymedia support and told that I ordered internet for 1 address but need to receive a modem on another one (because of I'm moving to new flat) and support told me that address is changed and modem will be sent to my current location.
But since my last call time ~10 days past. That's why I need to understand what's going on and what do I need to do
ask at support for number to track and trace your delivery online.....
you can try to chat from unitymedia homepage.... upper rigt side :
