Help with Re-Tail cross-DS Bells transfer

So, I listed an item for the 27,000 bells and had my account on my sister's DS come over and buy it while I was still in the shop. I then sent my 2nd account home which prompted a save for both of our DS's and then I exited the Re-Tail store with my 1st account and saved again.

My 2nd account has 0 bells and has the foosball table still, but my 1st account never received the payment and Reese never mentions to me that my item had sold. I also checked my bank account at the ATM in the post office and there's nothing deposited to my account.

What do I do?
