I would take you mom's $300 and forget the trade in. You really want to get on that roller coaster ride. You can be done with Samsung today.
The way Samsung operates, you might not even get the $425 charge back, nothing surprises me with Samsung.
Yup, they will just charge your card another $425. They probably have a hold on the card for that amount in case you don't send it back.If I don't send it in they will charge $425 right? I mean they won't send it to collections or blacklist my Note 8 would they?
