Who called from 4086185130

This number calls all hours of the day, and when you call the number back it says not in service,  wtf.

Dental services.  called at 11pm. received 3 phone calls.  when called back , phone not working.

This number is calling my cell phone repeatedly all day long... every day ... for weeks now.  How can I report this and to whom???

Waited for them to call back, I answered and told them if they called again I was going to turn them in, haven't had any more calls from them.

I don't recall this number and I want them to stop calling me.
