Quelle Fromage, so sorry to hear this. I too have been a victim of Tie Crafters. I spilled coffee on a relatively new CSGM and dropped it off at my boutique for cleaning. I knew they sent the items out, but assumed because the cleaner was good enough for Hermes, it was good enough for me. My CSGM came back with a 6 inch broken thread right in the middle. I was horrified as I saw that thread waving at me. Ugh. Luckily, the shawl was from a season previous and H replaced it for me. I've heard horror stories from my SA of lost and ruined scarves and H has had several conversations with Tie Crafters about their "work." But H continues to send stuff to them.Update on my ruined Brazil Bandhini - Paris cannot repair it. I'm very sad about this. They are looking to see if any may be left at any store in the world (unlikely, I think this was a 2015 release?). If not it sounds as though they will give me a credit.
So word to the wise, if your scarf cannot be replaced (ie is an exceptional or limited edition) be wary of giving to after-sales unless you know exactly what is happening with it.
Now I am too paranoid to take my things for cleaning, especially my CSGMs and grail 90s and when I do, my SA takes photos of all parts of the scarf to verify its condition. Since that time I have only had 1 scarf cleaned and because I again spilled coffee on it. (Maybe I should consider not drinking coffee, just to save my H scarves.)
I know this situation sucks, but maybe it could be opportunity to find a new and beautiful addition to your collection. Good luck!
