As youve stated, companies don't relocate to Asia to deliver equivalent quality, they do it to cut costs. And unfortunately if you pay less you will get a lower quality product.

A lot of simpler customers take their anger out on the CSR. I think companies even consider that to be a bit of a feature. They'd prefer you be angry at Filipino or Indian people and assume they're incompetent rather than blame the company itself. This was actually pretty common in the early 2000s. Thankfully more people have a better sense of awareness now and realize this is a more direct fuck you from the company to the customer and the CSR agent is just stuck in between.
