Bad service

A watched was purchased on the 16/10/22 for my sons birthday which was on the 24/10/22 . We were told to bring him to the store ( American Swiss Mall of the South ) to have the watched resized which we did on his birthday the 24/10/22. The person assisting us ( Sphamandla Manceda ) removed a few links and brought the watch back to us after 30min. While inspecting the watch I noticed that it had been damaged ( dented on the link of the wrist band. I brought it to Sphamandlas attention. He advised that unfortunately there is nothing he can do about it as he is not responsible for any damage to the watch as we requested for it to be resized. This is unacceptable as we paid for a new watch, was told that it could be resized in store and now it is damaged due to negligence of the store.
