I got a call on my cell phone from this number. When I called it I got a message that this number is disconnected or not in service.

It is a collection agency.

I have been getting the same calls, but it is for my husbands ex-wife.
They won't remove the number from their call list. When I asked to speak to
a supervisor, the guy said that I don't get that privilege.

So I called him an a**hole and hung up.
The a** crack called just after 7am

Got call from them and they were some explore company

I got these annoying calls from this number around 7:50 AM Sat when people are still sleeping.

This is  CC Collections Agency
