Professional Credit Services

I had a bill that slipped through the cracks when I moved, I owed it I paid it. But they lied to me and said the bill had been mailed back as a ploy as to why it was in collections. when I called and talked to the utility they said nothing had been mailed back, so I confronted the collection lady and she back pedaled and said they tried to mail me a letter and it had been mailed back due to them putting the wrong address on it. I paid them, this was my fault..... but there is no need to lie to me about mailing me a bill.
