I have muted and deleted this person. But then they get on an alt and keep it up. They have even stated they will make more alts to keep harassing me.

I paid 1800L for photo services and they never provided any of them. I have tried for several weeks to get in contact. Now this resident is saying Oh Well, Have a Good Day. Is there anything I can do? 1800L is alot to me and I feel this is wrong for anyone to do to someone.
