LexisNexis SA taking payment without correction of incorrect e-book downloaded

Terrible After Customer Service. I phoned the Sales department explaining and showing them the Jackson and Stent 2016 book I was placing a order for on their website, showing clearly the image and the correct ISBN number. I made it clear to both consultants that I have the Adams and Richardson book in hard copy. They send instruction how to download the ebook. A person can not check what book is going to download until it is downloaded. The moment I checked and saw they had downloaded the Adams book that I already have, I phoned the consultant and showed them again, they had downloaded the wrong book. It has been two weeks of me constantly emailing the customer department requesting a correction with no results. They either need to pay the money back to me OR download the correct e-book I ordered. This is so frustrating, I will never order anything from Lexis Nexis again.
