Allied Interstate LLC Debt Collection Complaint

Allied Interstate LLC Debt collection department,

Other (i.e. phone, health club, etc.) Cont'd attempts collect debt not owed Debt is not mine Texas

I moved in - 2015, cancelled - and returned equipment. - soon sent me a bill for $280.00. i tried talking with - supervisors, etc., that nothing was owed. They finally sent it to the credit bureaus ( late 2015 ) and I filed a dispute. Credit bureaus found - ' claim not valid and cleared it off my credit history. I thought we were done with this but last week I received another notice from Allied-interstate. I feel like I 'm being intimidated into paying them to just go away. I 'd like this to stop. I let them know during the investigation I knew that they could be sued for $1000.00 if the harassment continued, and it did stop for 9 months, but here we go again.
