A man received a letter from a credit provider about an outstanding debt. The man pointed out to the credit provider that the debt was not his. However he received further letters and phone calls from the credit provider about the debt. The man could not persuade the credit provider that the debt was not his, and complained to us.The complaint raised an issue under principle 8. Principle 8 requires agencies to take steps which are reasonable in the circumstances to ensure that personal information is accurate, complete, relevant and not misleading before acting upon the information. It was obvious from looking at the information on the credit providers file that the man was not the debtor. We asked the credit provider what steps it had taken to check the accuracy of the information before pursuing the man for the debt.
