Received a phone call from the number ( XXXX ) XXXX at XXXX on XXXX/XXXX/2016. I answered knowing this number was a debt collector that I tried to reach yesterday with my confirmation number showing that I had paid my bill. Yesterday after waiting on hold for 15 minutes I hung up waiting for them to call in the morning ( which they did every morning 6 times since XXXX/XXXX/2016 ) I was greeted by someone who was clearly out of sorts and was arguing my name. I told him that my name was XXXX XXXX not XXXX, after that was cleared up I was transferred to another male. He told me the reason he was calling and I told him that I tried to call back yesterday to give them the information but was put on hold for so long that I waited for their call today. I was not yet at my office to give him the confirmation number. He went on to describe how the money could take up to 30 days to transfer to them. I told him that 's fine but he could take me off the list. This seemed to catch his attitude ( rude ) He stated with a very snide tone " no '' ending with " I hope this does n't have any affect on your credit. '' To me that seemed like a threat. I understand that they have a job to collect, however there is no need to be rude or threating. I asked him his name and extension followed by the name of his manager. He mumbled a name and the number quickly. I asked him to please repeat that. Then he wanted to know why I wanted that information? I told him I did not appreciate his tone. He then went on the defense.
