This collection agency was trying to find my brother. After numerous times of refusing information to them, I found that if you fax or send them written notice to stop calling you, they must according to the Fair Debt Collection Practices Act (FDCPA). By the way, telling them on the phone isn't enough; it has to be in writing. Their info is as follows: SKO Brenner 841 Merrick Road CS9320 Baldwin, NY 11510-9320 Phone Fax toll free If they continue, they are direction violation of the law and can be prosecuted for such.
