Former Comcast cable technician here. I was an in-house tech, and corporate has ludicrous quality standards and nitpicky, white-glove QC's after an in-house tech leaves a job. However, the company obviously employs a TON of _independent contractors_. Some of these contractors are excellent at their jobs, but a lot of them aren't, and as they're not subject to any real oversight by the corporation, you really don't know what you're going to get. At least, this was the case at the office I worked out of. Based on my experience (and I worked at the company for a while), this is almost definitely 100% true, but it's probably a contractor or an individual corporate tech being lazy, instead of malicious action on the part of Comcast.
