Bad Service

We struggle to get any service from FutureLearn Impaq. I live in Gabarone, Botswana and have ordered these books for my little girl who is now going to Gr 4. I ordered school books from them on 30 November 2018. Pay everything. I still didn't receive the books. The Courier (Aramex) who FutureLearn used, lost the parcel. Now both, Aramex and FutureLearn said that they can't help me. Nobody is willing to help. I am prepared to drive from Botswana to collect new books in Centurion, but FutureLearn refuses to negotiate with me personally.
