Ambit Energy Complaints
My niece is an Ambit Energy Consultant. She has 46 customers so far, without a single complaint.
She herself has been on Ambit Energy for almost two years and has had no complaints herself, even with the company going through radical growth.
There doesn't seem to be much to complain about. With Ambit Energy you apparently only pay for KWH usage and the tax. Complaints would seem to be related to dealing with customer service, but as stated above, for herself and her 46 customers, no complaints so far.
