Debt collection — Phoenix Financial Services LLC (AZ)

Debt is not yours. On XX/XX/XXXX, I received a letter from Phoenix Financial Services stating that I owe {$820.00}. That same day, I sent out a request to provide proof of debt owned, with my signature and details. On XX/XX/XXXX, I received another letter, without any information I requested. On XX/XX/XXXX, I received yet another letter from XXXX XXXX XXXX with some cryptic CRT Code/Modifier and the date of XX/XX/XXXX. Once again, no explanation and no proof of debt owed.
