Been with samsung over 16 years! Have my laptop, TV , DVD, and cellphone made by samsung. Had trade in for over 4 different cellphone devices from samsung 6 to s7edge to note 8, to note 10 ultra to s23 ultra. Never had any issues with them until TODAY. Someone claimed that my Note 10 ultra is not eligible for a trade in (spacial after they charged me for that) so I requsted from them to send me my old phone back so I can trade it in with IPhone. They have been trying to charge me extra $500. I requested from them to return my old phone but they ignored my email. Today they sent me text warning me that they will lock my phone, so I gave them a call and spoke to customer service. The customer service is very BAD , I have never felt it like this with samsung. Now it's ti.e to just wait for the old phone to arrive and replace it with IPhone.
