Recently, I have been having some issues with a product. To sort this out, I sent an email from my company account (I live and work in an English-speaking country) to the manufacturer's customer support (the manufacturers is also based in an English-speaking country, as far as I am aware) explaining what the problem is.
To my surprise, the reply was in a different language than my original email in English: the other person saw my name, assumed what my native language would be and replied to my email in Italian (Funnily enough, they even have a "preferred language" field in their contact form, and I selected English there, too).
Now, the assumption was correct, I am Italian and Italian is of course my native language, but I think this is wrong on several levels. First of all, I might not be a speaker of that language, for all they know, I might be a person from any country who just happens to have an Italian name. Second, and probably most importantly, I might have to share that information to my colleagues who have the same issue, and they definitely don't speak Italian.
Am I wrong in thinking this is rather unprofessional and even impolite? Should I make it clear to them?
EDIT: as pointed out in the comment section, by "making it clear to them" I do not mean "calling them out on their unprofessionality", I meant something more in the form of a constructive criticism, so that they won't do it to other people. I know it is not my place to do so, and the focus of this question is more "is it unprofessional?", but I'd like to have different views on this.
EDIT 2: I am asking this mainly out of curiosity, I obviously do not mean to escalate things for such a minor non-issue. Also the "unprofessional" and "impolite" should be regarded as "minor" and "funny", not as something that would make me say "I would never work with them"
