Customer Reviews for Internet Service Providers in California
Customer Reviews
A Oakland, CA Customer
XFINITY Cable
July 24, 2025 Honestly, I wouldn’t recommend Xfinity WiFi unless it’s your only option. The internet itself is okay when it works, but the real headache is everything else, the customer service, the billing, and just how shady it can feel dealing with them.
From the start, I felt like I wasn’t being told the full picture. The reps will quote you one price, but then you’ll see all these random charges pop up on your bill later, such as activation fees, equipment fees, TV channel fees (I don’t even own a TV). It’s like they purposely leave out details just to hook you, and then charge you for stuff you never agreed to.
And good luck getting someone to help you fix it. Every time I called, I’d get bounced around to different departments, and no one ever seemed to have a straight answer. They’ll say one thing on the phone and then something totally different shows up in writing. And they’ll lie and say you’re getting the best price.
Cancelling feels impossible. They’ll try to keep charging you even after you return the equipment, and if you’re not paying close attention, you might not even notice.
Overall, the whole experience just feels like a trap. It’s overpriced, full of hidden fees, and the customer service is more frustrating than helpful. Definitely wouldn’t recommend unless you’re okay with constantly checking your bill and arguing with representatives.

Sonic Fiber
April 13, 2024 I think Sonic is a decent provider considering the quality of service when you compare it with the price point. I had Verizon FIOS at my old apartment which was alright but not as fast. I can’t comment on the price of Verizon because my roommate was the one paying & already was a subscriber when I moved in. If I moved to another house in a region Sonic services, they would be one of the ISP’s I considered most heavily. I enjoy their customer service as well, and the technician who came out to install the hardware was friendly.
