I feel targeted at my job

Al

I got a new job as a receptionist at European Wax Center and I just feel targeted, I'm not sure what to do. ive been here 2 months and all the waxers are making things up about me and telling them to my boss (She won't believe me when I say it's not true). I was originally working 5 days a week and now I'm down to 2 days and I'm not allowed to work by myself anymore because of how many supposed mistakes I make while working alone. I'm so irritated someone give me advice please
