Vodacom Woodlands terrible customer support

I upgraded in June. After a great pitch by the salesperson, I opted for my current phone to get the ear buds that was on promotion. I had to register on an app to claim this, which I did without delay. Working across borders, I arranged to pick the buds up from the store as delivery could not be arranged for obvious reasons. Four months later, and as many trips to the WOODLANDS VODACOM, I was informed that I will not get this, as the promotion has ended. SAMSUNG has been equally useless in their support!! Vodacom: I will be changing ALL my contracts very soon!
