Telkom is robbing me on my Samsung Galaxy S10+ Pre-order

I recently Pre-ordered Galaxy 10+ on an upgrade of my existing contract online. It arrived on Friday, and I've been trying to get a hold of Telkom ever since to find out how do I get the Samsung Buds that are advertised with the pre-orders and also the Samsung Original Accessory voucher both which are supposed to be valued at R3500!

I chatted with the Agent online on their website and they refused to help and insisted I dial 10213 or 10210 to get assistance with this. Upon dialing the numbers and eventually speaking with agents, the line either cuts off or the people on the other end just keep cutting the call.

This Pre-order is only valid until 7 March 2019 and I received my device already, WHY HAVE I NOT RECEIVED THE BUDS AND THE VOUCHER YET?!

I feel like Telkom is trying to rob me on something that I am supposed to have already gotten! I'm paying a lot for this contract and I expect to get what I pay for!
