XXXX has been attempting to collect on a non-existent debt. I have at all times had all outstanding balances paid on all accounts. I have proof of payment for the amount they allege is owed ( attached hereto ). A different collection agency previously tried to collect on this account approximately 1 year afo. I contested the claim, and that stopped contacting me. Now a different collection agency is contacting me to attempt to collect on the same non-existent debt. XXXX has agreed verbally on the phone that I owe no debts, and promised a letter of confirmation which they never sent.
