OMG that is awful! Honestly though, bleaching dark hair can take a few attempts to get right, it kinda sounds like they hadn’t properly bleached if it was still an orangey colour when they started to put the blue colour on! I don’t know much about bleaching dark hair but I’m sure you’re supposed to let the bleach work before you colour it again??
I’d say you have a poor hairdresser tbh. Hope you complained!!
