When I called to make an appointment, a woman answered and said Please stop and hung up on me. I texted the number to let her know I was trying to reach Carte Blanche teeth whitening. No response. I called the other number associated with this business and my call was sent to voicemail. If this was a mix up, it was extremely unprofessional. Customer service so terrible as to hang up on a prospective client is a huge red flag, causing me to wonder in what other areas are their services lacking. Beware.
