Not picky at all! All starts and stops need to be anchored that’s longarming 101 and is to be expected! I would firmly yet politely ask for a refund. How did you pay for it? I know credit cards can be disputed when there are issues with services. Have you used this person before? How did you come to use her? Has she been in business long? Does she have favorable feedback/reviews? I’m certainly not a professional longarmer, but if this were my business I would offer you either a refund or a redo at my expense including ripping out the areas in question. I’m sorry this happened to you, I’m sure you’re very frustrated and dismayed.
