Most technical help I have had is from Sky and the Indian technicians are very good.
The only problem I have had with them is changing contracts and having to hear so much stuff which isn't their fault.
This Summer I booked a holiday online, unfortunately the website only allowed me to book either 2 double or 2 twin rooms, not one 9f each.
I had to phone up and they were useless, eventually I got put through to the supervisor,(An American) who claimed to be able to so things out.
He asked if I was from " the kingdom" which I've never heard before and claimed to have problems working out the time difference.
All the phone call achieved was a survey asking how he'd done. I never got the phone call back and he didn't do anything at all.
I ended up having to contact the hotel myself to sort things out.
Americans have problems with non American accents in general. When I was over there I had to talk well posh and enunciate everything to the max.
No such problems in Denmark and the Netherlands where English is their second language.
