In the Spring of 2016, I experienced the worst and most chaotic Customer Service imaginable from Frontier Communications, here in the DFW, Texas area, I had responded by telephone to their start-up advertising while transitioning over from Verizon; I can't remember any difficulty with Verizon, however, I had no choice at the time because of a business deal... The following is my recollection of the problems (per my files). I received a letter where it was admitted to slow billing by Frontier, which caused a build-up of unsuspecting amounts! A. On my first contact, I spoke to Sales, as I explain in the following e-mail. I agreed to change over from my other service at what I thought was a reduction in the price since I was showered with incentives and promises designed to have customers change. Below please see my first response email (after months of awful service) from the person (Teresa) that was to handle my complaints. This only occurred because I posted on Facebook a detailed complaint of my issues.
