The fact they carried an ongoing communication with you shows they do care about the mindset of their customers, even if you don't agree with their message.
I'm not sure what you expected to accomplish, though. Do you think they would just acquiesce to your gripes, and let you establish the price of their products? Did you expect their apology? Or were you just happy to vent your frustrations?
I mean, really, I like to consider myself a humanist. I care about my community and the general welfare of mankind. But it should not be deemed an affront to humanity or decency, when a business doubles or triples the price charged for product x, if people are willing to pay it.
