JUST NO SERVICE AT ALL FROM ARISTATA

I placed an order for books at Aristata books only to receive an email that the one book is not available and I can get a full refund or I can take a second hand book. As it is a matter of urgency I indicated that I will take the second hand book. Heard nothing. I phoned Aristata yesterday 5/02/2025. I was promised that somebody would phone me back. No call I phoned again today and was told that a Andrew will phone me back. Still waiting. The tasks at Brainline is starting on Monday and we have no books. Maybe I should worn Brainline not to make use of this bookstore anymore. I need a resolution YESTERDAY already my whole shipment of books are being held up because of this
