So the battery is dying in my Treo phone (which is out of warranty), and I went to the Sprint store to see if I could get it replaced. The person at the store told me that they couldn't replace it, and (of course) tried to sell me a new phone.
Last night, I emailed Sprint customer support, and I got this response from them, which I quote verbatim:
Dear Thomas,
I will surely assist you with your concern regarding the battery.
Since the battery is out of warranty, it cannot be replaced.
You need not worry. I am here for you. You can go ahead and purchase the battery.
Once you get the new battery, just write back to me with its price, I will verify the price and apply the credit for the price of the battery (on your account.) I hope that I am able to bring a smile on your face.
Is there anything else I can assist you with. Thanks. Have a good day!
Austin C.
