I have bought several sd cards online which i had thought were made by sandisk but however i soon realized that after receiving them that they are counterfeit. How do I go about reporting this? They do not work properly as they should which in return prompted my further investigation leading to my conclusion that they weren’t even made by sandisk extreme they have the appearance of the actual sandisk extreme micro sd cards however it says shandian extreme 
Hi @DLDdesigns1
We regret to inform you that the memory card is not an authentic SanDisk brand retail product. Request you to contact the place of purchase for the replacement of this card.
