I need a gamertag change due to harrasment

If you're being harassed, you need to file complaints on those gamers and block communications with them so the enforcement team can take care of them.

You can find instructions on how to change your gamertag here - https://support.xbox.com/en-US/my-account/manage-gamertag-and-profile/change-xbox-live-gamertag You
do have to pay for gamertag changes.

You can set communications to friends only which will stop the harrasment.

As the others have said,you will need to pay if you want to change your gamertag.

Yes I'm being harrased by a lot of people because of my gamertag and I already changed it from the free one and I don't have enough money to change it what should I do?

You will not be able to get a forced gamer tag change unless it violates the CoC or ToU and to me it looks like it doesn't plus with the new policy you will have to pay the amount that it's asking for sorry :l

Solution is quite simple.Block communications with anyone harassing you over xbox live & file a complaint against them via your console.You can even set communtications to friends only.

Even if you did get a forced name change you would be given a random tag & would still have to pay to change it.

Like TrippIE says,your name does not violate the CoC so you will not get a forced name change,if you want to change it then you will have to pay just like everyone else.
