951-318-1650

I got a call from 951-318-1650. They left a very generic message not identifying who they were. I called the number and it is California Energy Solutions. I was going to tell them to stop calling but "their mailbox was full" real professional!

These a**holes call almost everyday.  I have told them REPEATEDLY to stop calling and informed them I am on the DNC list.  They could care less!

They call almost every day and multiple times.  They hang up and leave no message.  I am on the DNC list. That sure as heck doesn't help much, does it?  

how do I file a complaint against this company?

You can file complaints here:

https://www.ftccomplaintassistant.gov/
https://esupport.fcc.gov/ccmsforms/form1088.action
https://complaints.donotcall.gov/complaint/complaintcheck.aspx?panel=2

Also go to your states PUC pages, there should be a page where you can file a complaint with them also.
