Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The answer to your question depends upon what phone co. provides or provided that number. I have no access to records regarding phone #s or the billing regarding them, myself.
I would say, contacting the phone co. that may be billing for that number, would be a good idea.
If you let me know what phone co. it is, I can look up their contact # ***** you... but it's probably right ther on your bill.
Let me know if I can help advise you further with this matter.
