In my old apartment, I have been offered a 5G device to increase the speed, since I moved in 2025 and got a new contract, I dont need it and I want to return it. However, the new contract and the data does not show in the app and the device is not shown so I cannot select it for a return. I am still paying for it and I am not using it at all. 

Can someone help please to resolve the issue?

EDIT: It seems like someone did something so now I can see it.  However, I cannot only select the 

5 G Receiver SE to return, it has to be a package with the speedport. I dont want to return the router just the 5G device, anyway around this? 

Thanks
