I’m a new Verizon customer, I signed up for the 4 devices unlimited plan and upon checking out it offered to apply a $300 Verizon Gift Card that can be used towards accessories or Verizon bill. I have not received anything since check out. No email ,no further instructions, nothing! I’m seeking help like how do i redeem this offer they gave? Because my lines have been active for 2 weeks now and nothing!
