New employer, T

Got a postcard from them saying I want to renew my corporate discount. Im confused because the last time I spoke to a CSR a few weeks ago they told me I would never have to do it again since I had already re-verified it awhile back. New employer does not offer the discount. This discount is the only thing keeping me Along with them, if not for it I would just join my familys Verizon plan.

Is there any way around this? If I threaten to switch to Verizon (which I will do) will they let me keep the discount? Alternatively, I graduated from a university that has the same discount – would that work or do they verify that youre still an active student?
