The Book Depository non refund and no response for my inquiry Gloucester, Nationwide

"The Book Depository is awful store . 

March 20th, morning , I ordered two books but while waiting for showing up order conformation site, something wrong happened ...... over 5 minutes I waited but finally my PC was frozen. Later I ordered again.

I was afraid that I might order same books twice and asked customer support to make sure and cancel one order if there are double orders. Customer support just sent cancelation notification about order BDA-010-04761169689 and never mentioned another order BDA-809-93761266545 active. 

I checked my order history and knew there was BDA-010-04761169689 cancelled. Still now BDA-809-93761266545 has nat came up in my order history,

Later I ordered same books at Amazon com (I live in California , USA).

Next morning, on 21th, I got notification about order BDA-809-93761266545 and they said to me that ''Nineteenth fashion in detail' was dispatched (shipped ) and I could not cancel this ... I have to receive it and return it from SF USA to England. After they receive this , they will refund book fee on my credit card . Also they don't pay returning cost from SF, USA to England.

Many times I asked why this happened, why my order history can not show up order BDA-809-93761266545, why I need to pay returning cost from USA to England even though I have no way to know order BDA-809-93761266545, Customer support just said that they can not assist this case any more. 

Also I read another review, same double order happened and he returned one book from Australia to England, it past 6 months, they continued to say ''they have not received it yet and they can not refund him". Finally he gave up collecting refund !!

I am so afraid that same case will happen and I can not get refund about book at all. 

I am still thinking that book Depository must pay refund book and returning cost from USA to England.
