SAMSUNG GALAXY TAB A

I app**** for a Galaxy Tab A on the 26th September and was approved the same day. I was then told that there was no stock but one will be ordered for me. I accepted this but today I learned that there is no stock available in South Africa. I cannot complain about the service I received in the branch. My problem is how can MTN advertise an item but there is no stock available, also nobody can give me an idea of how long it might take for new stock to arrive, I think this is pathetic to say the least.
