Bought Used Apple Watch – Unable to Pair Due to Previous Owner's iCloud Lock

Hello, I recently purchased a second-hand Apple Watch from Sahibinden.com. The watch was bought only a month ago, and it came with the original receipt, box, and everything else. However, the person I bought it from forgot their iCloud account and password, and now I can't pair the watch with my phone. I’ve emailed Apple and sent them the invoice and all the necessary information, but I haven’t received any response to remove the iCloud lock. This situation is extremely frustrating, and I’m asking for Apple’s assistance to resolve this issue as soon as possible so I can use the watch I purchased. Please help me get the iCloud lock removed!
