Came here to get a 2nd job for weekends only for pulling orders at Fashion Nova. Started the 1st day and they had me doing other things and I brought it up to their attention but they didn't seem to care so I ended up leaving cause I didn't apply for general labor work. Been over 3 weeks close to a month and they still have not payed me for all my hours I worked the one day. Every time I called they said they will put the hours and never do. Really unprofessional
