The best way to return a modem from CenturyLink is to do Live Chat to get you shipping label sent to you. It is a prepaid label sent by CenturyLink. At the end of the conversation do not close the chat box. Go to Snipping Tool in your accessories on your computer and copy the conversation. Especially make sure you get the RMA # recorded/copied. CenturyLink can track your modem in house by the RMA#. Also, save your tracking # you are given and check to make sure the modem was delivered. You can use the Snipping Tool to copy the page that shows your modem was delivered. Also, to keep your hard earned money in your pocket write down the serial and model #s down and SAVE them. Since CenturyLink sent you the shipping label they can track the modem from their end but there is only a short window of opportunity to do so as the info is only saved for a month or less.
Video you packaging the modem and taking to your car and also video dropping it off at CenturyLinks preferred carrier(transport Co). Keep as much info as you can. Also, put the burden on CenturyLink by telling them to track down the modem as most likely they have it. They have a record of the shipping label they sent you with the RMA # on it. If the people in receiving did their job they will find it! Plus, ask if the modem is insured and make the insurance company pay for the "lost Modem".
CenturyLink should send an e-mail to you when your modem arrives but they don't. That way you would have a record of it if you save the email! Also, the instructions that CenturyLink sends do not tell people to save the RMA# or copy the shippers web page that shows delivery (using the Snipping Tool). I would argue in court that the Modem is the responsibility of CenturyLink after it leaves your hands as you no longer have control of what happens to it. It is their RMA# on the Shipping Label and their shipping label. They can track it from their end all the way to receiving. Maybe a class action suit would get the results for a nice drama free return and some money back in every ones pocket that has been truthful! Truthful people deserve Justice and to not be ripped off by bad business practices! Good luck everyone!
