I personally feel it is always better to respond. At least then it looks like the business cares about their customers!
Most of the time I ask for the person to contact us via a private message and then a day or so later I’ll delete the comment, but only if it is truly inappropriate for the page. Otherwise we can respond with something that say’s ‘thank you for the opportunity to resolve this issue for you’ or something like that.
