exactly -- coinpayments handled the transfer in question, then sent me back to Overstock, who told me that I need to e-mail Coinbase customer support.  I'll try to call them. -- thanks

I tried to make a bitcoin purchase on Overstock.com last night, my first ever crypto purchase. It was easy to execute the Bitcoin transfer (just held my phone up to a barcode on the computer screen), but eventually I got an e-mail from coinpayments.net telling me that the transfer timed out and the transaction was cancelled, and to click a URL in the e-mail to get my refund.  So I did that, filled in the info they asked for, then they told me that I need to contact Overstock.  So I called Overstock customer support, who told me that I would have to send an e-mail to Coinbase customer support to get my BC back.  And I happen to know that Coinbase customer support is unresponsive, so I'll give up on this one.   Was a small purchase I was making just to learn the mechanics of transacting.

Is this a common occurrence?  It's frustrating, although I'm still bullish on crypto.

Thanks all for the ideas and advice.

I bought this BC on Coinbase.   I just looked for a "WITHDRAW" button or function and couldn't find one.   I've set up a wallet at BRD and if they can't help me move the BC there then maybe I'll try an Electrum wallet. 

BTW, you mentioned that Electrum would give me a "receiving address" -- BRD gave me a "QR code" -- is that the same thing? -- thanks

I'm trying to move it from the exchange to a wallet but I don't know how.  I e-mailed customer support at the exchange where I bought and asked them to tell me how to move the BC to a wallet, but they weren't helpful.   So I'm e-mailing customer support at the website where I got my wallet and they're a little more responsive, but it's kind of slow-going.   Hopefully I will figure this part out eventually.

Thank you all for your replies, that is helpful.

So there is nothing analogous to a serial number on a currency bill, got it.  Thanks.

Hello -- I am completely new to crypto currency.   About a week ago I purchased some Bitcoin on one of the on-line exchanges to try to learn the mechanics of how it works.    There are so many tutorial resources available, but I don't really understand them.  I need to learn by doing.

My initial question is:  is the Bitcoin that I purchased represented by any unique digital information, so that I can point to what is "mine"?  If so, how do I get that unique digital information?  I've asked the support team at the exchange this question, but I can't get an answer.   Appreciate any guidance on this question that anyone can provide.   Thanks.
