email
dan@sprint.com if you have had bad customer service.. email and email often ( evertime you have had a bad service call )
REMEMBER be nice !!!
Be educated, respectfull and to the point. DONT lie, just tell your story as it happened..
This may not help your cause for now but it will get them looking at your email and your complaints ...
If you dont get a responce its okay ..they got it ....
