I made an online transaction, details mentioned above to SHEIN online shopping. The transaction amount got deducted from my account (A/C No: [protected]), and the order was not placed. I had to approve another transaction one minute later in order for my order to get placed. In normal, circumstances, amount gets refunded. This time it did not get refunded. Try contacting the customer service multiple times. No response. There is not phone number as well.
