Who I have the same questioned this topic

My wife and I switched to Verizon back in November with the promise of $250 gift card for each of our phones. It has been 4 months and have not received my gift card. I am being strung along from the rebate center and it’s beyond frustrating. At this point, I am extremely unhappy with Verizon. I have called 4 times and keep getting strung along. Has anyone experienced this? Who can I contact to file a compliant? I don’t want anyone else to fall for this as I did.
