Worst Online Shop

I placed an order last evening successfully but 1 hour later, to my surprise, Asos email me stated that they unable to process my order and my order has been cancelled and to complete my future orders.I'll need to send them the following:

-A copy of your passport, ID card or driving licence.
-A copy of your payment card statement dated within the last three months, clearly showing your name and billing address. Please blank out your card number, but leave the last four digits visible.
-The delivery address and the name of the person who will sign for future orders. If this is a work address, please provide the company name.

I never meet such experience like this in other online shops before. It is really ridiculous.

I try to purchase once more last night and the status of my order until this morning is only "Received" , not "Order Processing". I try to ask Asos care so many times with no obvious answer.Finally, I cancel it and reorder the item for the third time!!
Guess what?? This time the status of my order still the same,only "Received" and after 3 hours, I got the same email from Asos stated that they unable to process my order and my order has been cancelled and to complete my future orders.I'll need to send them the following:

-A copy of your passport, ID card or driving licence.
-A copy of your payment card statement dated within the last three months, clearly showing your name and billing address. Please blank out your card number, but leave the last four digits visible.
-The delivery address and the name of the person who will sign for future orders. If this is a work address, please provide the company name.

This will be the last time I shop with Asos.
Never ever again I want to deal with such annoying online shop that cause nothing but inconvenience to its buyer.
