Trade In Return slip

I also got an email and text stating that they are reviewing the trade and will let me know in 20 days. It seems long to review this time around.
I got the same letter with the same time frame , but 3 days later I got the all ok etc.
 
Sent mine in last Wednesday, email received Friday from Samsung that they received the trade in. Got notified today that trade in was accepted and completed. Pretty quick this time around.
