Not willing to help

I ordered a book online and after I ordered it I realised it was a digital copy. Their refund process says no refunds on digital products. My issue is that it was not clear that it was a digital book. I sent them a mail and all they did was throw the Ts and Cs at me. I said to them I have not downloaded the book, which I haven't and I was willing to spend more money buying the hard cover. They ignored me and resolved the case. Instead of making more money and keeping an existing customer happy, they have now lost a customer. Poor form and poor customer experience. And because they don't respond on HelloPeter it shows how they treat their customers
