Calling this Comcast Customer Number

Jeff Whelpley is the editor / author responsible for this content.

I'm in the process of opening a new small bakery in the Brighton area right outside of Boston, and one of the tasks I need to take care of for my business address is the internet and phone service. Anyone from the area knows that Comcast is the logical choice if you want to go with a provider that has a big reach and plenty of options. Before setting up my service, I had to talk to an agent because this was my first time buying anything as a business and I wanted to make sure my needs were met. 

Given this was the Comcast business side of the company, I imagine that they get a ton of phone calls daily for customer support and troubleshooting issues. While no one likes downtime, a business can't sustain any type of downtime when it comes to internet or phone lines. Therefore, I was prepared to wait a bit, but to my surprise, it only took about 2.5 minutes to talk to someone and figure out what would work best for my business. I know people complain about Comcast, but honestly, it's hard to beat their great customer service. 

When I first called, an automated voice picked up the phone and said, "Thank you for calling Comcast Business. This call may be monitored or recorded. Enter or say the zip code where you have or want service." I entered my zip code which the system said it didn't recognize, which wasn't a surprise to me since I wasn't a customer yet. It had no reason to recognize the line I was calling from or the zip code I put in because I don't live in Brighton myself. That's just where my business is. 

The voice assistant told me, "Sorry, I didn’t find an account based on your zip code. I’ll need an account number or a phone number to look you up, or if you're calling for a new account, say a new customer." I repeated new customer as instructed, and it reaffirmed that the call was for setting up service for a business which I confirmed.

There was a brief pause for about 20 seconds with nothing happening, and I thought for a second that maybe I was disconnected. While I was trying to figure out what was going on, Ray picked up the phone and asked what he could help me with. He made the sign-up service easy and was polite and clear about all aspects of the contract. Plus, it only took me about 2 minutes to get to him, so it was worth my time for sure. 

Jeff truly believes that all customers deserve good service. He’s been building tools, inventing phone tree hacks and helping customers since before his days at GetHuman. He's also a Google GDE and involved in the Angular community.
