creditor collection issues BK

I have a creditor that showed up at creditors meeting, it did not go well for them. The trustee told them they needed to follow bk law. the creditor when leaving the court room started to yelling at me we are going to sue you and cursing. It escalated that I had a deputy sheriff intervene. The sheriff told them they needed to comply with BK law. The creditor keeps calling for their property. prior to creditor meeting I went to creditor 30 days prior, they mentioned they knew I was in BK I paid the bill and nothing was said until creditors meeting. They keep telling me they are going to sue, the company is a leasing company called Aarons. I work in law enforcement and I think the management for the store has issues with law enforcement, ( possibly either ex con or knows someone in prison ) since it is pretty much a prison town. I work the local jail in Florence Arizona. I filed the BK myself without legal help but, it is now becoming a issue.
