Zero assistance or customer service

I purchased ebooks for my son's online schooling and could not download it to his pc. I downloaded to mine. Afterwards I realized my ADE was did not have an ID and I could not transfer it to my son's pc. After dozen's of calls and emails, I got no help from them. Only an automated message saying they can't help. I must try adobe. Adobe does not give support to people that uses free software and directed me to a forum, which did not help. I then contacted the publisher, Oxford University Press Southern Africa , which just sent me back to Takealot. I have NOT finished registering the books and still need to submit the Vendor ID. I am thus at a loss on why they can't cancel it and send it to another pc. I do know that I have never had any problems with fiction books and easily got books deleted and sent to other devices. This of course is an educational book and they know I'll have to buy it again. I can't believe between Takealot, ADE and OUP they are very unwilling to assist me.

The book I'll have to purchase and can't bypass OUP, but maybe I can buy a secondhand book. Takelot account I can just close.
