Failuer to meet a fulfil promise an deilver GearVR

On the 18th march is bought Samsung Galaxy S7 from Vodacom, on the same day I followed the required steps to claim my GearVR reward, everything went well I must admit, as I got confirmation within reasonable time. on the 4 April I received an email advising me of a delivery of my parcel on the 7 April. I waited the whole day for deliver without any luck, when I call worldnet express to track my parcel I didnt get help. Today call them again and I am told the Samsung has put a hold on all deliveries, this is not acceptable as the only reason I bought into your brand was because of the offer your company made and now you are failing to deliver as promised. I will appreciate it if I can get what was promised to me before end of today.
