As many have pointed out, the trade in offer ($350 off an S10e) by Samsung.com is a scam. My perfect LG V30 was denied for false reasons, and after 2 weeks of delays and runarounds, I wrote a physical letter to the Samsung CEO. After 3 days, I got an email that my trade in was totally acceptable.
Then, I used my 800+ points (=$4 off) to order a micro SD card on Sept 2. It is now Sept 15 and it still have NOT arrived. Tracking said it was due the 12th, then 13th, then 14th, now is saying the 16th (UPDATE: scratch that... NOW saying 17th. My guess is it will be the 31th of Sept... yes, I know, Sept has only 30 days, but then again, we are talking about Samsung). UGH.
