Comcast customers filed more than 2,000 complaints against the company from April to June, according to documents released by the Federal Communications Commission.

The documents were obtained from the FCC through a Freedom of Information Act request by CityExplainer, a Baltimore-based blog. CityExplainer yesterday posted an article about the complaints and made them all available to read in a spreadsheet and PDF.

There were many complaints about data caps, billing problems, service outages, slow speeds, and poor responses from customer service representatives.

"You’ll see senior citizens and others complaining about unrelenting billing errors, people complaining about alleged data throttling and data caps, and residents’ sad tales of dealing with technicians who come—or don’t come—to their homes to fix problems," the blog post said.

Some consumers claimed Comcast is violating net neutrality rules, though this was often due to people misunderstanding the FCC's regulations. One person claimed that Comcast "charg[ing] more for faster Internet services... violates the regulations on net neutrality," which is not correct. The core net neutrality rules prohibit blocking, throttling, and charging Web services for faster access to consumers, but not different price tiers for home Internet service.

Comcast is the largest cable and broadband provider in the country, with about 22.3 million TV customers and 22.5 million Internet customers (with a lot of overlap between those two groups).

TV, phone, and Internet providers are required to respond to consumers who file complaints on the FCC's complaint site. As we've previously reported, customers of Comcast and other companies have sometimes had better luck resolving problems by complaining to the FCC than to the providers directly.

Complaining to the FCC isn't foolproof, though. A Florida resident on June 27 told the FCC, "Comcast disconnected my account without reason or notice. I am disabled homebound. I moved in to my house and for 2 weeks had no new Internet service after setting up my new account. I called several times. They told me the modem was the problem. Then I called today to say there was no signal to my home. They said my account was cancelled. I asked why and they said there was no reason. I was never notified."

The customer posted a few follow-up messages saying that Comcast had gotten in touch but not solved the problem. "I still have no service and the FCC representative at Comcast never called back as promised," the person wrote on July 1. "I now have charges and have never had service. Additionally, Comcast has added TV service to my account even though I only ordered Internet for 14.99. This is the second time they have done this without my permission. It seems like an ongoing game with their office."

Even if not every complaint is resolved, Comcast employees are reading and responding to them. "We reach out to every customer (by phone and sometimes e-mail) who files with the FCC to see how we can address their concerns," a Comcast spokesperson told Ars. "We then respond to the FCC with a letter explaining how we resolved—or tried to resolve—the issue, and also send the customer a copy of that response as required by the rules. If the person isn’t a Comcast customer, we copy them on our written response to the FCC as required by the rules."
