yep had the same thing happen to me,it only took 12 days for mine to die but i got a new phone the next day(on a sunday 😳 )an they upped the warranty to 24 months. its been 3 weeks know an so far so good.
Was that a VZW store Rep or the Customer Service Rep? That is really hard to understand since you took advantage of the their rebate that replacement is affected. The VZW store gave me a new phone when my speaker blew without any questions....but I didn't get the rebate mailed in time. 🤭 I was not advised of any warranty change if I did get it mailed though. Seems totally unfair!
