Received a voice mail from an XXXX XXXX stating she was from XXXX XXXX XXXX XXXX. Said she had a summons to deliver to me and would be there Friday morning between XXXX and XXXX and wanted to be sure I was there. Also called my mother and demanded she contact me. My mother said please do not call her she was told they have every right to call as she was listed as a reference and the only person who could take her off would be me. I called th number given in the voice mail XXXX XXXX XXXX. I was transferred to a man who refused to tell me what this was about and told me he will continue to call my mother as he has every legal right to. Told me that he understood it would be hard for me to understand since XXXX XXXX has XXXX of the lowest XXXX 's in the nation. Said I was a XXXX debtor and he was sure I was getting calls from other people because I was XXXX and I didnt pay my bills. I asked what this was in regards to he said we just need to know if you will be home Friday cause we have been there before and no one was home. Told him they have called me before and he said that was a lie and that I was a liar. I asked him again what this was in reference to he refused to tell me. He continued to berate me and call me XXXX and a low life etc. This is clearly a debt collector and the number is registered to XXXX XXXX. If this was a legit legal issue there would have been a local number and the address they are trying to serve me at isnt my current address it is my ex-husbands house. If it was XXXX XXXX County they would know my address. My ex works from home and said no one has ever been there before and said this is a scam and to report it.
