Promises not honoured by Samsung

I purchased a Samsung S9 cellphone in May 2018. Samsung offered a free cordless charger and a 128gb memory card. I duly registered for this gift and kept following up. Towards the end of June I was told by Samsung rewards that my gift had been given to the courier for delivery. I followed up again a number of times and was given the waybill no and name of the courier company. The courier company has not been of any assistance and kept promising to deliver. I followed up with Samsung rewards who advised they can't help me and I must follow up with courier Company. As I never contracted with the Courier Company surely Samsung should resolve as they appointed the courier. Based on the poor service received, my next cellphone will not be a Samsung.
