Worst Customer Service Ever

I've been dealing with an ongoing issue with my landline—calls drop, followed by a busy signal. After wasting countless hours navigating Xfinity's automated system, my problem still isn't resolved.
Yet again, I requested a callback, only to be transferred, and guess what? Another recorded message saying my wait time is 23-30 minutes. So I opt for another callback, only to repeat the cycle.
The language barrier adds to the frustration—when trying to get a resolution, clear communication matters. And after 12+ years of paying $259 per month (internet, cable and land line), this is the service I receive when I actually need support?

Also, what if someone can't type, doesn't speak English fluently, or has a physical limitation preventing them from writing out a complaint? Why is navigating support such an impossible task?

Xfinity, this needs to be addressed
