I have had the same experience as others. I went to the My Verizon site to pay off my S10 so I could take advantage of the pre-release offer on the S21+ from Samsung. On January 16th 2021 a Verizon chat person named Kambria said she could get me a better deal than Samsung. She stated "We can get you $600 off with trade of S10 for S21+, plus $200 from Samsung; that is $8.33 per month for 24 months." I assume that this would represent a verbal contract that would be honored by Verizon. I only learned later that the $600 off was contingent on enrolling in Playmore for $10 per month. So I reluctantly enrolled in Playmore and Verizon added the $10 fee immediately. It has been more than 3 months and my monthly line bill is $83.39. Obviously I didn't get the $600 credit for my S10 trade and did not get any credit from Samsung. We contacted a supervisor named Sarah Barlow who said she would fix everything and nothing has changed. I have spent hours trying to get the offer I was promised with no one being willing or able to help. So I was not able to take advantage of a legitimate offer from Samsung and have received nothing from Verizon. I can't believe Verizon would allow this type of business practice to continue. Please straighten this out!
