Whoa-oh.... centurylink doesn't have stores you just bring their equipment back to like comcast does (not that it matters, I returned all my shit back to comcast when I was like 21 and they still fucked me for like $300-400 months down the line lol).
You have to wait for them to send you a pre-paid mailer then ship it back. Shit... I'm going to have to buy a fuckin GoPro and record myself doing all of this stuff, have witnesses and a paralegal witness it or something so i dont end up getting screwed again
