Phone Issues

I woke up this morning to a phone that won’t even turn on or charge even on the charger.  I got online quickly and talked to a gentleman on ATT chat and found that my phone is still under warranty so I decided to get a new battery under warranty.  I will receive it on Monday at the latest since ATT has to have time to get the package sent my way.  If it is NOT the battery, I will replace the entire phone.  Thank goodness for other forms of communication when calls coming in or going out isn’t possible at the moment.  I hope it is the battery and NOT the entire phone but if it is what I think it is…then I will have to communicate with ATT again online.
