Thank you for bringing this to our attention. From the information you provided, it sounds like a warranty exchange was the right path to take but the store may not have handled the situation properly. I'm sorry we had you go to the store to get your replacement and you ended up walking out with the same phone that won't turn on. I hope that by now you have a working phone. Has this all been cleared up yet? If not, I recommend reaching out to Customer Care or T-Force here so we can get this squared away.
Thank you for the comment. However, if a store does not comply with the guidelines of the protection plan or T-Mobile, it appears the supervisor and store manager should be properly trained or fired.
