Returned Phone Tendered to Returns Agent

I decided i didnt like the device and returned it on the 20th of December. I bought it on a Next Plan. I tried taking it to the store and they called customer service at the AT&T store and couldnt figure out how to return the device because they didnt carry it in the store. They told me my only option was to return it through the mail. So they boxed it up for me and i took it to the post office and got a tracking receipt but a day later its saying it was delivered to the returns agent. So now i have a new wireless bill generated paying for a device i no longer have. Please help.

Also, it was purchased online through AT&T.

So are you telling me to contact the Post Office? All theyre going to do is tell me to contact AT&T.

Ok, the Post Office said they no longer have tracking on the package due to it be tendered to the returns agent. They stated this is where the package is given to a 3rd party carrier designated by AT&T or whatever company creates the return label so what am i suppose to do now?

Hello @Silversurfer20,

Thank you for that information. We recommend tracking your package through the Newgistics Tracking page. Let us know if you have any additional questions.

Yeah, i found that website, but im not seeing any information any different than the post office. Shows where it was tendered to teturns agent just like the post office. It says not received, ship date unknown, reference number unknown, destination 56901. Thats it.
