Unknown to me, XXXX XXXX XXXX XXXX sent my closed account to a collection agency, Credence Resource Management, LLC. XXXX XXXX XXXX had not informed me of any bill due. I had no idea. In the meantime, Credence Resource Management calls me over a XXXX times a day from different phone numbers. They do n't leave messages and when I answer they will not tell me what the call is about. I asked and they said they could not disclose. These people have called day and night, weekends, evenings, mornings, at all times.
