Customer service only on-line

I called a phone number and got stuck in an automated loop. Comcast does not have humans answer the phone anymore. If your replacing your modem and your xfinity mobile charges for data., how do you activate a new modem? Baby boomers do not all have phones they can put the wifi ad on, and many are not computer savvy. Do you really think the only way you can deal with your customers is an automated help telephone line.
The next time I have problems, I’m switching to AT&T.
