T-Mobile USA review: Insurance

First off there was poor network coverage in many places I travelled. I was in a train derailment in rural Missouri in the summer of 2022 and it seemed like my phone coverage was the only one that did not work, I had to use other people's phones to even make a call which is ridiculous. There was many places I travelled to that did not have service but other carriers did. I then was bought a phone after the train accident with my account and same phone number, paid in full by Amtrak, in which I bought the insurance when I first joined T-Mobile in 2020, which included a screen protector free to be replaced at anytime. When I tried to get one again after I got my new phone I went to T-Mobile several times and the service reps all said my phone was no longer eligible for insurance even though I paid for it when I first bought into the account. This was very upsetting being that I bought the insurance and the customer service said it never expires, I was then told I would recieve a free screen protector for my troubles in the mail but never received it.
