Spire collection
may be contacting you because your original creditor has given them the task of recovering what you owe them.
If you get a call from Spire Recovery, do not panic, instead, go through your records to confirm if the debt is actually yours. You could ask the debt collector to send you a debt validation letter to prove that the debt is yours. You also have the right under the FDCPA to ask the debt collector for information like their name, address, and the entity they represent.
