I was trying to order a laptop. I place the order, money was taken from my account and few hours later I got a call that the order was cancelled. I asked why and I was told that I failed internal security procedures. When I asked what does that mean I was told that they cannot tell me but I was EXPLICITLY asked to place the order once again. I took yet another few min to place the order. Once again everything went fine, once again money was taken from my account. I decided to check my order status on my own few hours later and once again cancelled. Lady from live chat once again told me that I failed internal security procedures. When I asked why she did not knew. She just assumed that it's because billing address and delivery address was different. If that is the case why was that not cross-checked BEFORE taking money from my account ? No answer. Right now I have double the amount taken from my account and no laptop. My assumption is that they put on the website items they do not have in stock and when I've place the order they try to order it from vendor. When that fails you fail "internal security check". That would be acceptable but not in a situation that they do not state it clearly on page. Also even after the call I am receiving mails from ao.com encouraging me to track my order and I did actually not got any mail confirming that my order is cancelled and my money will be refund, despite the fact I asked for a written confirmation.
