Sorry you’ve been ‘misled’. I can’t help, but reading your story reminded me of a similar situation my cousin got into with Fender.
He bought a USA Strat via GAK. He’d chosen the guitar because of the spec (can’t remember exactly), but when it arrived it didn’t have the solid steel tremolo block, as promised.
There were other differences, too, (parts made in China) and the whole thing became a farce. Fender offered to change things on the guitar, including the block, but the new steel one didn’t fit!!!!!!
After 3 months of emails, etc, the guitar was returned and refunded.
Seems that sometimes, companies manage to fulfil their orders by ‘utilising other stock’.
I think you should dig your heels in and get what you asked for.
