I 've repeatedly contacted this company advising them to provide me with verification of debt. They repeatedly tell me that they are not required to provide such debt verification and that they sent XXXX out on XXXX XXXX. I 've advised them multiple times that I did not receive this letter they sent and they refuse to provide any other. I have advised them that I am not opposed to paying what I owe, once I receive the verification of said debt. They refuse to provide this information repeatedly. They have not provided this and refuse to offer a resolution.
