This is a collection agency that calls, so far, from about 7 DIFFERENT local numbers it has had access to. I have been returning all calls I have received to find out who they are and they have all been to the same company. They talked so fast all I could catch was something like "Inversion Outsourcing Agency" or something to that effect. I, once again, referred them to my bankruptcy attorney, for the SIXTH TIME that day and said goodbye and added them to my spam contacts.
Yep, collection agency - this one sent by T-Mobile for a miscommunication between one of their store managers and headquarters about a discontinued account ;-(
