I had two Samsung S21+ cellphones unlocked, moved to Verizon. One Voice Mail worked, other did not. Spent hours with Level 2 and Engineering. Told I needed a Verizon phone. Just traded up for two Samsung Galaxy S22 Ultra. Voice Mail does not work on either. I contacted Verizon, thought we had fixed but did not. Contacted AT &T for new service but need old S21s which were received last evening. I can return S22s within 30 days but old phones cannot be returned. Nothing they can do. I attempted to upgrade to S23s b, which was agreed to on old terms, but the Rep could not keep service price the same. I want to go to AT&T but trades are worth $1,000 each and I can't send new S22s as I will be charged for them. I cannot reach any corporate office. Help!
