Cellphone cover for a Huawei P9 Lite Phone

Brought a cellphone cover from the Vodacom Gardens Centre Shop, in December 2017. At the bottom of the cover where you charge your phone the flap did not close properly. I took it back with my receipt, but did not have the box for it in which is came, because on that day the young gentleman who fitted the cover for me disposed of the box. Anyhow the cover was replaced but, the old cover that I brought back was politely put back into the box from the replacement that was given to me. This was then placed back onto the wall, for resale.
