Oh no. I feel her pain. Such stress. I rang ACCC, and then I lodged a formal complaint with my state consumer protection / fair trading (I’m in WA), which is still on going, but they have agreed to repair under warranty, after originally saying I was up for repair costs, just waiting on confirmation it includes the shipping. I had it less than 6 months.
I went to the Givenchy store when I was on holidays (we don’t have one here) they can do a side by side comparison and give you feedback, and spot anything that doesn’t match their bags. I would get her to contact the store she purchased & request it is repaired, under warranty. Feel free to contact me directly if you’d like. Wish her all the best, I’ll never buy from them again.
