A Verizon agent has just advised me that I have to keep the device I brought in on a BYOD promo for 12 months. If I upgrade or trade in the device, Verizon will impose a chargeback on the rebate that I received for the promo. I do not see this stipulated in the BYOD terms and conditions. All it says is that there will be a chargeback if the customer terminates the service contract with Verizon within 12 months from device activation. Could you please clarify and confirm whether the agent I spoke with gave me the correct information? Thank you.
