We closed out our XXXX phone bill and paid them in full On XX/XX/2020. However received a bill on XX/XX/XXXX called XXXX to confirm and told us we didnt owe anything and they are applying credits to accounts for over paying. XX/XX/XXXX credence called my work phone and it was there first attempt and I asked why did they call my work number and I dont owe anything to XXXX and I have confirmation. They harassed me and told me me I do owe them and it was sent to them today and I need to pay it. Called XXXX  back and they told me to pay them and they give me the credit back and so I did. I think this is wrong I have never had a collector call me to owe money and call me at work. It was embarrassing and even though it wasnt my fault and I think this was wrong and very unprofessional Account number Credence Resource Management # XXXX XXXX XXXX XXXX XXXX {$120.00}
