ok to further clarify , I sold an item of jewlery  ( a bracelet ) , The bracelet I sent macthes the description exactly as in the invoice

Now the buyer has let me know there is a "kink" in the bracelet, I know there was no kink as I checked it before I sent it and packed it correctly before sending it. I also have many photos of the bracelet which prove it is in perfect condition

I personally feel the buyer has changed their mind about the bracelet, so is now making this excuse up
