This number is now tied with multiple sellers on E Bay selling Chinese Knock Off Samsung Memory Cards.  The real person behind this number is Zack Murray from Allentown PA,  His real number is 484-809-9978.  Unfortunately this individual has many IDs on Ebay Selling 256GB and 512GB Samsung Micro SD Cards.  When you receive one of these cards and try to use it the card only accepts about 8GB of data and corrupts the rest.  He also has an email [email protected].  He will try to convince you that these devices are authentic and so on.  I spent a considerable amount of time on the phone with Samsung.  At this time they do not even produce the 512gb and 256db modules they are selling on Ebay.  The outside of the packages they are selling look real but when you find out the package does not have the size of the card printed on the package and there is no bar code printed on the back you quickly realize how it is a knockoff.  The back of the SD card itself has a model number printed MMB3D08BUACA-GE LD8H89160701 Made in Taiwan.  When you look up this card it is manufactured in China 8GB.  Be extremely careful if you purchase any memory cards on ebay I have found almost all are Knock off Chinese Fakes.....
