I have had several frustrating connections to representatives in India. The main problem is that many of them don't realize they are speaking too fast.

I explain that they do pronounce words differently from the way they are pronounced in America, so I have to figure out what is being said and if they talk at high speed then I don't have time to figure it out.

Problem is, of course, that they don't realize the pronunciation is at all different and is based on both the sounds of the mother tongue and a partial emulation of British pronunciation. I'm convinced that if training included talking at a slower, almost normal clip, there'd be less frustration.
