Who called from 5592726410

no message..but got 3 calls from this number

I have gotten several calls from this number, not sure how to locate which phone company owns them so I can report the abuse.

Repeatedly recieved calls from someone or something identified on caller ID as "YPR".  Never leaves message, if call answered, there is no responce.

Got another call today. They called once on Thursday. It went to voicemail and no message was left.

Same deal with me.  no message.

They're out of Fresno, Ca.
Telephone company is Pac - West Telecomm
I'm not willing to pay for the reverse phone detectives to tell me who they are.
If anyone complains, or finds out more, please repost.
