It was 10am, I just woke up thinking it was someone I new from Rhode Island. It was a aggressive phone call asking if "Mark" was there. I nicely told the lady she had the wrong number. She yells back "I get you don't live with Mark but can you at least write a note for him!" I replied again, "You have the wrong number, I don't know who this Mark guy is." and she said kind of in a robot voice "okay, I'll remove you from the list." then i hung up. Possibly could be spam.
Got a call from this number today. Yesterday it was 4014063695, one digit different. I keep on getting calls for a woman named Debra on the number I got from TMobile. It's been over 3 years and I'm still getting calls for this woman. Last year, I got to talk to someone reasonable and told him to remove the number from their list as it's now not owned by Debra. For about 3 months, I did not get any of these calls so I thought that was it. Then the calls started coming again. Turned out, what he probably did was to just give a grace period for the collection so the calls stopped for a certain period of time but they did not really remove the number. I think I will still get calls for this Debra person until the day I die. This was the second number I had from TMobile as the first one also has a lot of debt calls.
