Wrong delivery and painful process with wrong information and no clarity

I had ordered a new connection online on June 26, however my wifi device was delivered to a wrong address on June 29. I raised a complaint with UPS but they never responded. 

I then reached out to Xfinity and they arranged for a device pick on June 30, which I picked up and activated my connection. 

On July 2, UPS delivers the device to my address which they had delivered to a wrong address. I reached out to xfinity support, to inform about this extra box which is delivered now and I want to return.  But the associate was not able to understand anything and was misguiding me. Told me to visit the UPS store and show the chat ID and drop the box there. I told her how will they accept without a return label but she was just not understanding. So I picked up the phone and called Xfinity  , the person on the call asked me to call UPS to generate the label. 

I reached out to UPS, they are saying Xfinity will generate the label. 

There is no clear information and just misinformation. I was honest to report this device and thought of sending it back but instead of receiving proper information and support I am just receiving wrong information. Should I just dump thi

s in the garbage ?
