She's definitely right that the quality of their support has tanked. I've had significant connection issues where people on other carriers have none and their support personnel sent me useless boilerplate questions after I requested support. They then followed up with a multi-page incoherent trouble shooting doc that seemed aimed at their own engineers. One of the worst support experiences I've had, even from Google.

When I first signed up they had fantastic support, now it's worse than what I expect from Comcast.
