When my vintage jumbo needed a minor repair I took it to Bond St and they took care of it. Nobody asked for any receipts or cared where I bought it from, they'll take care of genuine Chanel no questions asked. It was ready 24 hours later and they even cleaned the bag and polished the hardware which I didn't ask for. I couldn't pick up the bag myself so they posted it to me. I paid the postage cost but there was no charge for repair.
Loony is that old bond st ?
I will let you all know, i am not happy because the bag is so new and i feel like Chanel should really not be like this !! - It's the most classy and sophisticated brand around and yet some of my lesser bag's have lasted me years!
