AliExpress Pocket service has been terminated since June 26th, 2019. And as a result, any balance left in the account would be returned to the original account of the payment. For instance, if you used credit card to pay for the gift card order, the refund will be made to the same card.
Most of the refunds have been processed already, while some are being processed by our technical team. Pease accept our apologies for the inconvenience.
