I will never buy on Alibaba again, because I was scammed: I activated Letyshops cashback before paying, and the answer was that I didn't. It is a scam!
Good morning Alexander!
In your case the cashback has been activated, but the purchase has not been made as foreseen by the conditions of the shop to receive a cashback. We hope that such situations do not happen again and you will receive cashback for all your purchases in the future.
