I’ve been an Optimum customer for over 6 years, paying my bills on time and staying loyal even when others warned me about their poor service. Unfortunately, my latest experience proved them right.

In September 2025, I upgraded from 300 Mbps to 500 Mbps. The agent assured me I could switch back anytime if I wasn’t satisfied. The very next day, I called to revert to 300 Mbps and received a confirmation email that the plan change was successful — even showing a $17.33 credit.

But my October bill still showed the 500 Mbps plan, and I was charged double — $80 instead of $40. When I contacted support, one agent had no clue what was going on and kept giving me runarounds. 

The supervisor then claimed my downgrade failed because my modem was “not compatible” — which is ridiculous since I’ve been using the same modem for 4 years on the 300 Mbps plan with zero issues.

It honestly felt like they were just making up excuses to keep me on a higher-priced plan. No notification, no accountability, just scripted apologies and sales pitches for Optimum Mobile.

After this, I’ve completely lost faith in Optimum’s customer service and billing transparency. I’ve never seen a company work this hard to frustrate loyal customers. I’m seriously considering switching providers after this experience.

Hello,

The email telling me my order had been delivered asked for my opinion on the delivery/shipping.

In a word?  "HORRIBLE"

Why?

Nassau National Cable staff had no interest whatsoever in making my life anything but a living annoyance.  To use only UPS to ship is awful ... it's limiting, expensive, and in my case causes delays as well.  Needlessly.  

I live in Alaska.  The order would have cost AT LEAST $187 to ship here with UPS. (which is more than the cost of the cable I was buying).

It would have cost "maybe" $44 to ship it here with USPS, and I would have had it already.

Instead, it cost me almost $40 to ship to a warehouse in Idaho with UPS, which, by the way, was higher cost than the online shipping estimate ... this arrived at the warehouse today.

Then they are going to repackage it, and send it to me.  The cost will be $5 for their efforts, and whatever the actual postage is ... which ... being Flat Rate Priority USPS, will be around $40. (FYI, was more than that, so I chose Ground Advantage, causing more delay ... but had I got NNC to send me this via USPS Priority, it would have been here last week, and it would have been cheaper than the overall cost is now)

You could have saved me time and grief and money, but you did not care to.  Your staff seems to simply ignore everything, and I spent a week trying to work it out.

I do not like you very much at all, Nassau Cable!  It's too bad, too, since you have lots of great products.  But I make it a point to avoid companies that ship using only UPS (or FedEx, for that matter), as it limits options, is more expensive, and is often slower, while costing more.

(I've sent this as an email to them, twice now)

Incredibly quick response time in resolving my issue. I called at 12:25 and my internet connection was back by 12:39. 

I love how all subscriptions are combined in one. So many different selections for a great price !

We’ve had great customer service and a very good competitive price through Everfast. 

A high quality cable.  The price was very reasonable with a quick turn around time.  I appreciate that I can get almost any length I want.  That makes it a lot easier to avoid cable clutter.

These guys are superb. Genuinely the best customer experience I have had in a long time.  I was upgrading the DC system in my boat and ended up needing 11 custom marine cables of varying length, cross sectional area and lug size.  I placed my order on a Tuesday at 9pm and I received a message by 10am the next day that my order had been shipped.  Two days later I received my order in northern New York.  Every cable was exactly as I ordered, made with high quality material and with excellent workmanship.  Use these guys for your next project, you will be glad you did.

Once you get through the install, everything is AWESOME!  Great organization of channel line-ups.

Having great content running in the background creates a vibe—and Chipset TV nails the vibe every time.
