STOCK ISSUES - MAKING LEMONADE, BOOK BY LIANA SHAW

I am a South African author, whose memoir - Making Lemonade - was published in January 2024. Although the book has sold out on takealot.com - TWICE - takealot.com are failing to place orders to replenish stock from my publishers in the UK. Moreover, every time the book sells out, the title disappears from their platform, causing confusion. In the meantime, we are being flooded by requests from readers wishing to purchase the book. What do we have to do to rectify this, once and for all?
