Training of "Technical Support"

So I come from a technical support job. I deal with internet providers across the country all day for a living. I have never dealt with such under trained and rude technical support (I've had 6 contacts in less than 24 hours) as I have the last two days. None of them were able to speak in proper English sentences and when I caught "Charles" (as if this is his real name) in a lie, he just stammered until he put me on an indefinite hold. 

The lie Charles said was that my router was receiving the signal from Cox and that it was the router that was the problem. Unfortunately for Charles, I unplugged the router 5 minutes beforehand and never plugged it back in just to see what he would say. After this, I was put on hold for over 15 minutes and called back, received another technician (who luckily spoke English) and they acknowledged the issue on Cox's end and my issue was resolved in under 5 minutes. 

Charles called back later to apologize for the call disconnecting and that no supervisors were available at which point I terminated the call.
