So far so good.
“ Switched providers because the old supplier had rates that were no longer competitive. There was a brief glitch during sign up. Ultimately, the old account was shut down, and the bill was issued with competitive rates. ”

Excellent Customer Service
“ I wrote May 31, 2025 with frustration regarding my bill following my introductory pricing expiration. Today, 6/2/25 I placed a call to cancel service. After reading other reviews here I was expecting the worse but the service I received was exceptional. The associate I worked with, Angel x7308, was very attentive to my concerns. He was kind, patient, understanding and informative. He explained options and proceeded as I requested with nothing short of the upmost kindness. ”
