Everyone these scammers operate under the names of Bluetone/ Pulse Telecom/ NECC Telecom Scammers/ Volocall
They use a proxy phone number in New Jersey, they will not stop calling me and my best friend. They issue fake bills through their VOIP service and are based on Big Beaver Road, Troy Michigain. and use other numbers starting with "201 443"
They pose as a legitimate business but are running a fraud scheme, their websites appear one day and are gone the next to create anonymity. One note also is that they use social media and attack anyone criticizing them on these forums. If you get contacted call the FTC or local FBI office. Many who work there are from Eastern Europe and the owners are from Romania (a identity theft and fraud hot spot).
