Has anyone ever thought that there are indian people living in the US and may work at these call centers. There are plenty of times I have called in to Dish and get someone in the US that I just can't understand. I have troubles understanding people with southern accents a lot of times on the phone.
People need to slow down when they talk on the phone and learn to annunciate.
It can also go the other way. There are times when I get someone with a heavy northern accent and can't understand a word they're saying.
