I have had Internet service with Earthlink for many years, they have always given me the very best of service, Yes, they do seem to use some people whose English language is very good, but to me sometimes a little hard to understand, this can be beause of several factors:
My own hearing never having been perfect and some of them being from elsewhere other than from the U.S.A.
But that is only while talking on the phone and it isn't too much of a problem.
As to online help, there is no problem at all.
They all regardless of who they might be and or from where always have given the very best of service.
I have always been very happy with my ISP.
This is an Internet connection speed test:
I pay for 1.5 Mbps service, but am getting 2.58
