what is the main thing customers call in about?
Lastly, paying their bill.
me: Thank you for calling Sprint, may I have your wireless # please?
cst: Oh this is Sprint?
Lately though its been trying to get the credit for the restoral fee b/c they break their payment arrangements, lol, and feel they still shouldnt have to pay their restoral fee to get the service back on. *sigh*
After that, I'd say that probably billing issues of some kind are most common.
Then, issues relating to their online account. Most people can't seem to remember their user name or password or both and need to start over with it.
We also get a lot of calls relating to the phone not working right in some way; usually it's either a setting issue in the phone or the phone simply needs to be replaced ...
