If a debt collector is calling you repeatedly, you have rights under the Fair Debt Collection Practices Act (FDCPA). You can send a written request to the collection agency to cease all communication with you. Keep a record of the calls, including dates and times. It’s also important to dispute the debt in writing and request validation. The Kugel Law Firm can help you draft these letters and advise you on whether the collector’s actions violate the law.
