Customer Service agent put me off using this site

I didn't even get a chance to actually order from this website as the customer service woman that responded to a query I had was so condescending that I decided to not even try.

I sent an email to them stating that I was looking for a protein powder that is safe to use while breast feeding. The response I got was "We are not medical professionals...." and could not advise me. I am quite aware that an online website would not employ medical professionals to assist in the customer service department, thank you. My query had more to do with product knowledge and I would never seek medical advice from an online store.

Surely someone working for a company has knowledge of what they are selling? Was it necessary to use that tone when all I was asking was if they stocked one that they knew was made for breast feeding moms in mind? I really don't think it was an unreasonable inquiry, as the UK and USA both have brands made with this purpose in mind (I have searched for both in SA and cant find them stocked here). And if she didn't know, surely a less catty response would've been okay (Maybe something along the lines of "unfortunately I am unaware of one that is made for this purpose in particular") instead of stating the obvious.
