I think a support employee does not have the right to disclose the location of the office, he simply adheres to the rules of the internal policy of the exchange. By registering on the exchange you accept their rules.
Yes, they don't have and why would OP have to ask a question like that since Binance is reputable enough to give your trust to them to hold your cryptocurrency. But if OP wants to know the head office of Binance then i think OP deserve to know that but there are rumors already on where are their office, i think that's enough.
