Vodacom online upgrade

I upgraded online. The specific contract...Smart Top Up XS+...consist of a Samsung Galaxy S9, dex docking station, J4 cellphone with sim (new contract). Received my order last week. Only S9 and J4...no dex docking station and no sim for the J4. Upon my 4th attempt I manage to get the following response. I didn't upgrade to a contract that include a dex docking station...but if I check online ALL offers on the specific contract (Smart Top Up XS+) states "free dex docking station". The contract without the dex docking station is Smart XS+. The sales agent now want to tell me that it (docking station) was not offered to me because it is out of stoc**** although every single offer (on my upgraded contract) online includes it!!! Very very unprofessional I feel. Simply because there is no stock it becomes a case of "oh well, just leave it out?"
