The Quick Solution
You have a problem? I have a solution!
if you have a sprint online account you should be able to block the number from texts. or you can go to a sprint store give them the number and tell them they spelled the name wrong and when they ask "whats the name supposed to be? just tell them any name like milly or tom and then ask them the name on the account is like becky or something and then ask them whats the name on the account. if you get a buzy store they wont really think twice and may give you the name on the account. the address they wont give out.

Look at my name, it's all you need to know
Wow, let's not recommend committing fraud. Unfortunately you can't get someone's name just cause you have their number. Call care or go online and get the number blocked. If the calls are harrasing in nature and the caller ID is blocked then call the police.
