No, they are told to do it. I assume that their customer service system allocates the name and the logic is that people prefer dealing with an identifiable person rather than what it is - random people in various global call centres. So you ring up and the person who answers says they're e.g. Thomas Edison. You ring back later and maybe a woman in a call centre in e.g. Poland tells you she's Thomas Edison. And then maybe a few days later a man in a call center in India is also Thomas Edison. They all pretend to be the same person even though its obvious they're not!
