I absolutely reject your assertion that there is any net harm to be mitigated. Automated customer service reduces those moments where human interaction is required, but in the process frees up time for us to devote to more meaningful forms of human interaction. It certainly doesn't prevent you from interacting with other people, just frees you from the obligation of some fleeting encounters. And I personally don't find those encounters to be all that rewarding on average - a good customer service experience doesn't brighten my day much, but an avoidably bad one really kills the mood.
You should probably learn to accept the fact that some people want the option of having a business transaction be strictly business, without the overhead of social conventions of politeness. This does not make a person anti-social, it just makes them not so pathologically extroverted that they need human interaction (error-prone, and still relatively impersonal over the phone) just to order a pizza.
I never said there was any net harm; quite the opposite. Nuclear power is incredibly useful and relatively good for the environment, but there is the risk of meltdown. While it's a net positive, there are still issues that should be discussed and dealt with.
The fact is that much of our lives is spent doing things like buying things, eating out, et cetera. And for many people, spending your time doing those things without any human contact is lonely. It may not be for you, but you don't speak for everyone.
I absolutely believe in automating as much labor as is possible. Nonetheless, I think there is room for improvement in how society functions so that we get both efficiency and, for those who want it, human contact.
I do, however, reject your premise that automated customer service is better than in-person help. I am not an expert at checking out groceries in the same way that a cashier is. I go much slower through the process, and have to focus more on that. Right now, automated customer services largely serves to cut down on costs, not to improve service.
(I also never said anyone was anti-social. I do think that "pathologically extroverted" is needlessly insulting, and "need human interaction" is a strawman. I don't need a cloth napkin either; I just prefer it.)
