I switched to FIOS on November 1, 2017 after receiving an order number via email with a quoted monthly cost. When my first bill arrived it was substantially higher. I called customer service which reveiwed the quote and told me there was an error and they won't honor it. They informed me that I could cancel my service or pay $50 more per month. When I suggested that they correct their error by signing me up for the promotion I had originally tried to purchase (and which they incorrectlty told me I was not eligible for) they refused, saying that promotion was no longer in effect. The basic response, repeated by a manager at least 6 times, was "I'm sorry, but we won't honor that quote".
I intend to submit a formal complaint, with all of my documentation (I have copies of everything, including the on-line chat where I set up the new service), to an address that I found on the website for general correspondence, since there is no email or postal address for customer service issues. Does anyone have any experience getting an issue like this resolved?
