I had an Indian support call sometime last November, and that is using the term "support call" very loosely. I swear after struggling to understand WTF was being said for 5-10 minutes, I had to say, "I'm very sorry. I am as sincerely trying to understand you as you are trying to communicate with me. I haven't understood a word you have said and I am, unfortunately going to have to terminate this call. Thank you and Good-bye."

I was genuinely trying to understand him, but there was literally no hope.
