Hungry Jack's Australia review: given a meat pattie instead of a vegetarian

Ordered a rebel 100% plant based pattie and was given a meat pattie my daughter is vegetarian and has been for a long time .She took a couple of bites and was sure it was meat so we took it back and they said it was a mistake on there part and gave her a free meal which we had already paid for. My daughter is devastated I will be taking this further I myself eat meat and am gobsmacked how this happened
