I went to Courtney Co for a skin test on Thursday, ahead of getting my hair coloured on Saturday. The man who saw me (Steven) made jokes about my hair -- I'd previously had to colour it at home for a few months -- and was rather negative. I reconsidered having my appointment with him but decided to go ahead.
I arrived at Saturday to find all the chairs occupied. Stephen looked at me confusedly and shouted, "What are you doing here?" It turned out he had been trying to call me on Friday to rearrange my appointment (I don't answer my cellphone during work hours, and Courtney Co are not open outside them). As he didn't hear back from me, he told me that he'd cancelled my appointment -- despite me confirming it in person just 48 hours before! -- and turned me away with no offer to reschedule. I really wouldn't recommend going to Courtney Co, because it appears the man who runs it either double-books appointments or decides whether he'll see you based on whether he likes your appearance.
