Shocking service from ZANDO / JUMIA

What poor service! Returned 2 parcels on 24 January, confirmation emails received that they have received the delivered items but since then NO communication! My online account is not being updated, emails go unanswered, phone calls to follow up just say wait for another 2-3 days! Today your service telephone number is "no longer in service"?? How long does it take to do a refund?? Really if this is the level of service after your revamp it is absolutely shocking. Definitely not worthwhile shopping online from you!
