Jumping onto this thread, I'd like some advice about a client I recently had demanding a refund, she was a new client who had been going to another girl for "shellac", she noted her nails weren't in the best condition and two had broken right down the same day she came into me, while doing her nails i listened to her bad mouthing previous girls who did her nails, this made me feel uneasy, as the other 8 nails were extremely long I advised her to file back her nails to the same length etc, and also told her to apply cuticle oil daily to nourish the nails, when done she said she was delighted with her nails, next day I had missed calls, text messages, fb messages(I was with a client) saying she wasn't happy with her nails, I called her back to ask why she was unhappy, she said a nail broke causing the polish to chip, and felt she had wasted xx and wanted a refund, I asked her to come into me, I offered to fix that particular nail, and declined to give refund, I haven't heard from her since? I'm thinking she may be bad mouthing me as she had other salons during her app with me, was I wrong declining refund?
