The larger the organisation the greater their focus on cost-cutting hence "help" desks staffed with staff paid statutory minimum (or off-shore for a dollar a day) and pressured to close calls fast. A large business can afford to lose a few of their millions of customers (probably want to lose those who need a lot of support).
I've experienced excellent customer service using small local ISPs but then along comes someone like GoDaddy, buys them up and - well, time to move on.
