Terrible Customer Service

Seriously unimpressed with the service delivery from Lexis Nexis. I purchased an e-book for which the link to download the item expired and I am now unable to download the item at all. I have sent emails which have I haven't had any response to, I also made a call to their call centre, upon which the consultant advised that they cannot supply me with a new link and that I need to purchase the book again. I requested someone senior to give me a call, upon which I only received an email later that day from another consultant stating the exact same as what the consultant I spoke to over the phone said to me. I have still not received a call back as requested. It's very clear that customer service is not a priority to them. I would not recommend anyone do business with them.
