Horrible service and **** promises

I took a new contract with Vodacom end of June 22 for a Samsung Galaxy A73 5g. The special was that you will receive a super charge powerbank with the contract. Upon completion of the contract I was told that I have to go onto the Samsung M app to claim the powerbank. Now i'm already ****ed off, why does it not come with the phone, why do I have to struggle to receive the powerbank. Needless to say there was no voucher to claim the powerbank, I contacted Samsung and they advised that Vodacom was suppose to give me the powerbank, go back to Vodacom@carnivall which advises again that Samsung must supply the powerbank, but they will try to organise me one lying aroung............ NO I did not take the contract to receive a thing lying around....... I want the powerbank I was promised with the contract. After Months I still don't have the powerbank. Next time I won't take Samsung, but another brand that supplies the extra's immediately with the phone and I won't use Vodacom again also!!
