Aramex SA, zero service or care

Ordered a book from Amazon on 20 Feb 22, should have been delivered in May. As at 17 May, book still not delivered although Aramex has correct address and landline number. They won't try landline number ?! Won't try deliver! Received email from Amazon saying Aramex say parcel is undeliverable. Lengthy phone call to Aramex yielded little interest from staff, customer care is ludicrous!
