Hello!
Our service does not affect payment and order processing in the store. On the issue of a refund, we recommend writing to the seller or in support of AliExpress.
To accrue cashback during the promotion period, you could make purchases in two ways: add goods to the basket after the transition, and pay during the sale period; or place an order (selection, adding to cart, payment) within one browser session after the transition on November 11-13.
Contacted you in order to understand the issue in more detail. Unfortunately, they did not receive an answer.
Respectfully,
LetyShops team
