Company called " Portfolio Recovery '' keeps calling my home, sometimes twice a day ( evening, morning, weekdays, and Sundays ). Says we owe a debt and is requesting money repayment but we do n't owe anything. Calls have persisted for over 6 months. This is obviously a scam and based on the volume of Internet complaints, they are a known-seedy, aggressive " business. '' They use different phone numbers ( e.g., XXXX ; XXXX ; XXXX ; and XXXX ) making it difficult to block their number.
