Accidentally got the 256gb

Noticed immediately after ordering that the 512gb was the same price and contacted Samsung support to try to get that changed being it’s the same price… they told me that would cause an inventory issue with the preorder and the only option I have is to cancel the whole order and try again

The issue with doing that is I have already canceled one preorder due to missing out on certain accessories that were back in stock and haven’t gotten the money back from that and won’t for 7 business days…

Do you guys know the way around for this? TIA
