Comcast tech cut off my apartment and didn't even tell me why.

Today a Comcast tech came by this apartment and shut off my service without any prior notice and then left while I still had no service. 

I had to get a service call to restore my connection. So later today a second tech showed up to say the first tech found a problem with my line from outside the apartment and it was interfering with the system, so the first tech cut me off and left without even notifying me what was wrong.

I was left completely in the dark about them coming to cut off my access and then I was left in the dark about why they did it or when my access would be restored, until I made a dispatcher send out a second tech. All I was told was access was restored, no one volunteered to me the fact that my cable line was ancient until the second tech happened to let it slip.

Is it too much to expect a service tech to inform a business class customer that their internet has been shut down because of a faulty coax? Or at least send information up the line so someone else can let me know? If I hadn't pushed the issue I would have been sitting forever all day wondering why service was due to be restored at 3pm and yet I was still without service. The idea that I have to fight my way through Comcast's menu maze (getting disconnected 3 times with "good bye!" until I found the secret handshake combo) to get my service restored...

And where is the complaint email? I'd love to send email to someone in charge about this. I'm a business class customer working at home. I pay for better service than this. 

Is this supposed to be normal now for customer service?

Really?
