Misleading adverti*****t!

I went into Vodacom Atterbury branch about two-three weeks ago and app**** for a contract for the Samsung Galaxy S20 Ultra 128GB + Samsung Galaxy Tab A 2019 10.1" @ R969pm. I was assisted by Eugene who is very helpful and friendly (kudos!). However, I was called yesterday and told that they do not have stock and that it will take very long to get it. How can you advertise something if you do not have stock? I opted to wait for the phone and tablet as I am not going to pay for only the phone when I can get the phone and tablet for the same price. Please get back to me, I urgently want some feedback about when I can expect to be able to get the phone and tablet as ordered.
