My niece received a phone call saying they are an independent carrier in which the voicemail they left was saying they are going to come to her address and which they knew and find her in which she would need ID and a witness cuz they said they were serving her and if she was not home at this address then they were going to go to her family’s and to her work they left a number she could call and which she did and this guy said some threatening behavior about a past due amount of a bill she has over 3 years ago. What bothered me is that the phone she is on is her mother’s which is my sister and she passed away a few months ago and nobody would know she has that number. She’s a mother with two children and is very uncomfortable because she told them to mail whatever they have because she will not allow anyone on her property that she does not know. The phone number is 888-8345 9746 I am trying to find out if this is a legit number and when I call it the company says they are jwa and his name is Shawn Phillips. Should we be concerned.
