Optimum Fiber/Cable formerly Sudden Link.
The worst I have ever dealt with.
I had 1gig Internet and Cable with them. Constant box disconnects.
When the service when out you would wait for 45 min to an hour to get a rep, and then wait for days for a tech to come out.
The final straw for me was when we appeared to be losing internet often.
If I used a VPN, I could get online.
I figured out it was a DNS issue. It was hard coded into their gateway. Their support said there was no way to change it.
Then canceling took over 30 minutes with a rep on the phone who had to make up other reasons in here CRM software to let me cancel.
I tried to tell her that my call served as notice, and I did not want to spend the time online. She said, no way to cancel online, and I had to do it her way.
Oh... and I was billed for the next month due to their terms of service.
Worst company ever.
I switched to Fidium Fiber, which was good, and Dish for TV.
This month I switched to ezee fiber due to a promo, $49 per month for life, no extra tax or fees for 1gig fiber service. It's been great so far, and I actually get 1.6 gig down and 1.5 gig up at the modem.
Their customer service is excellent. Houston TX based, they speak English!
And... all of my calls got me to a live agent in less than one minute!!!
Highly recommended if you are in their area.
