T-Mobile chat rep lied about first responder eligibility

I would escalate this to executive resolutions team(or whatever they are called now) you can do that by contacting T-force online in chat and request escalation to the executive resolution team and get a case number. 

it can take 7 to 10 days for someone from executive resolutions to review the case and reach back out to you, if you are unable to take a call they will leave a phone number and a new case number on your voicemail and you can call back in and use that new number to navigate there automated system and actually talk to someone about the issue.

after initial contact, you can continue this on email with your documentation etc.

Now will they honor the what there employee said I can not tell you, but they do have the power too honor it.

T-Mobile should actually post covid come up with a combined plan, Tmo Military/First Responders and Nurses/Doctors and just call it Magenta Heroes. but they haven’t done that yet and under the new management they might not.

but here is the fine print on First Responders Discount. 

First Responders are currently defined as : “State and local law enforcement officers, firefighters, emergency medical response personnel, pensioned retirees as well as parents, children, or spouses of first responders killed in the line of duty are eligible for T-Mobile's Magenta First Responder plans.”  

The other issue with the first responder plan is it does not include Federal Law Enforcement, and it has to be reverified yearly.  Military plan is a one time verification and done.

Hope this helps.
