I am completely befuddled as to how to quickly pop out the drawers off their so as to have access to connect plumbing at back.

I called help line and they were unable to tell me on phone.

No instructions came with the vanity sink. Nothing on internet site about this.

I was told by the person I spoke to on the phone yesterday that I would get an email today with instructions -- so far I have seen nothing.
  
I need to get this sunk installed today.

Yu can call me. You have my phone number in your data base
