the customer pays and then receives what has not been ordered,receives something different possibly a fake/defective item/or maybe nothing at all.Also since the payment details are stored these thieves and criminals can take money from the customer's bank account and could be big amounts so my good piece of advice is DO NOT SUBMIT PAYMENT INFORMATION SINCE THIS INFORMATION IS STORED AUTOMATICALLY WITHOUT THE CUSTOMER'S CONSENT,customer's not ordering from them for sometime and all of the sudden transactions appear on their bank accounts for things which HAVE NOT BEEN ORDERED THEN, THEM NOT WANTING TO REFUND BACK THEIR MONIES OR REFUSING TO REFUND BACK THEIR MONIES IS INCONVENIENT AND THEY WILL NOT ACCEPT ANY RESPONSIBILITY FOR THEIR ACTIONS,SO VERY DANGEROUS TO STORE THE PAYMENT DETAILS OR TO ORDER SOMETHING FROM THEM(which the customer will be getting something different AND NOT GENUINE ITEM)since in china everything is being produced very poorly AND THEIR ARE NO FACTORIES WHICH PRODUCES ALL OF THESE ITEMS GENUINE IN CHINA ALL ITEMS ARE COPIES FROM GENUINE AND ON TOP OF ALL THIS FALSELY ADVERTISED SO MY RECOMMENDATION IS NOT TO TOUCH THEIR MOBILE APP APPLICATION AT ALL.
