So this post is 4 years old and there are still replies from days ago with dozens of people experiencing the same problem, yet only 1 or 2 have posted their resolutions. I just went through the same thing, so I want to share how my situation was resolved. I don’t want to repeat the same story that we see in all these posts; claim with assurant, receive new phone, ship damaged phone, get non-return fee on bill, contact tmobile/assurant, check tracking number, assurant claims they received an empty envelope.
After that, I went through multiple calls with assurant and tmobile, they each ran their “investigations” to find the phone, to no avail. Assurant pretty much cornered me stating that they received an empty package and that all I could do was file a claim with USPS.
Though the whole ordeal is so ridiculous, it was only at this point that I decided it was too much; why would i have to waste my time, trying to find a phone that I did my part with and shipped out? So instead of a claim with USPS, I went on the assurant website where they have a form that you can fill out to request information. I filled out my info, my claim number, and I asked for the name, phone number, and other contact info of the person who is in charge of my claim, so that I could properly list them as the defendant in a small claims court case that I would open up. NOT 2 HOURS later I received a phone call from assurant “corporate offices”. This lady said she could help me and that all she needed to do was track down the shipping info and see what the weight of the package was when I shipped it. So I told her I have the receipt and that it shows the weight was 8oz. She asked me to email a copy of the receipt, I did that within a few minutes, and that same night she emailed me back saying that she applied the credit for the non-return fee to my account.
I hope this helps others!!
TL;DR just contact assurant and say that you will sue… they’ll resolve your issue right away.
