Have traded in a Galaxy Watch 5 44mm when purchasing the Galaxy Watch 8.
Their website does not give an option to choose whether the Watch5 is Bluetooth or LTE.
Assurant have assed the device and claim a mismatch. They claim I stated it is LTE, and it is not.
I did not claim it is LTE. No where does it give me an option to choose which variant it is.
So just a warning to those trading in watches.
I bought 2 watched and Traded in 2 Galaxy Watch 5, the other was a 40mm. Still awaiting for that to be assessed but interested to see what they do.
I blocked my payment card and also, there's a 0 balance on it anyway (Wise).
I CC'd Comcom in comms with Assurant and Samsung EStore email.
Comcom have stated they have logged the claim for assessment.
The value is $10 but it's the principle. I understand others have had bad experiences with Trade ins too.

Good luck with this! I do the same as you—I use a Wise digital card for the purchase, and then delete the card after I’ve received my order or when sending in my trade-in device. So far, I’ve had two successful trade-ins, but it’s important to cover yourself just in case something goes wrong.
One thing I don’t like about the process is that, even though I select “no” for all the options about device condition—clearly indicating that my trade-in device isn’t working and is in poor shape—the paperwork always states the condition as “good.” That does make me a little nervous, but thankfully I haven’t had any issues myself.
