Is this ergo real? If not where could i get a third party authentication so i can return it?

I bought this bag back in December. I had it authenticated on one selling platform now it's being returned for be fake. I thought it real but if not then I need to get it officially deemed so. There must reputable places? Or is it even really fake?
