I wanted to buy a USB drive on the Ali Express mobile application. 128G flash drive (1), and I also proceeded to the payment but after placing my card details and clicking on payment. The new page loaded and said insufficient funds. In less than some seconds I was debited more than the amount I was ask to pay and yet the was still no sign that I already paid. My order was empty. I call the customer care but couldn't resolve it. Please be of help to me. User's recommendation: Nice app.
