No aftersale service for cash customers!!!! Very poor service!!!

I bought a ps5 bundle for my kids cash online. When it got delivered, it is missing the portable dual portable charger as advertised with the deal. I paid R11500 for this deal . I have been trying to contact Vodacom regarding this issue and have been sent from this department to the other. The is no Aftersale service at all for cash buyers. All the agents say they deal with contracts clients. So basically at Vodacom if you have purchased one of their products in cash , you are doomed. I have sent even an email to their eshop, no response. This is very disappointing and very frustrating, I have 3 contracts phones with Vodacom and this level of incompetence is seriously giving me doubts. How can an established business like Vodacom have zero after sale service for cash customers. Why do they even offer this service if they have intentions of maintaining cash customers. My kids are so disappointed they didn’t get the full package as ordered. Can someone please assist with this or take back your ps5 and refund me my money.
