As I see it, buying a product made in somewhere like India is one thing. But having
support for a product sourced there is a different matter.
I find that phone support is bad enough when it is 50 miles down the road, but when it's the other side of the world.....eeek!
I guess it would be exactly the same the other way round. No, there's nothing like having support which is accessible locally, wherever you live, and I've found that in the most part that the further it is away, the worse it gets. There are exceptions, but they are definitely in the minority.
Personally, I'd rather pay a little more for an item, knowing that I can get support locally, than source it cheaper, miles away and pay later when something goes wrong.
Anyway, I don't think this call centre is for support. I believe it is for sales, which is a slightly different matter. I guess it isn't quite as important where the sales centre is, unless it needs to deal with variable cicumstances and local customs. Then it would be a disaster not to have it locally.
A call centre is a
SERVICE, not a product. A slight distinction, but an important one nevertheless. I would apply different rules to manufactured goods, than I would to services. Like you say, a lot of goods are made in 3rd world countries, even for major brand names. However, I think most services tend to be handled locally, for all the reasons detailed above.
