Aesthetics Plus

This place is fantastic for training, however it only gets one star because I have never seen a place with worse customer service when it comes to sending out orders correctly. I have lost customers because they haven't been able to get any order right or deliver it in the time frame in which they say they will. When I point out that they wrote something different in their confirmations they become rude. How can they be rude when they are the people making the mistake in the first place?
