Smart device without access

I have received my FNB smart device 2 weeks ago and the SIM card is still not activated, despite all my calls and the wonderful follow-up of my personal banker. When I first called a week ago (Tuesday after the long weekend), I was advised that the SIM card would be activated the following day (Wednesday). On Wednesday I called again and they advised it would be activated that day. It didn't happen and I complained with my personal banker who immediately followed up and they advised it would be activated the Thursday. Also that didn't happen and I advised my personal banker on the Friday that it was still not activated. Late on Friday afternoon I received a call to advise that the SIM card has been activated and that the number allocated to the SIM card is ***. I tried several times during the past weekend to call that number, but it immediately went to voicemail and didn't ring on the tablet. I followed up again this morning at *** (option 6) where a gentleman advised that the SIM card has not been activated according to his system and that I will get an SMS within 30 minutes to advise on the cellphone number - it is two hours later and I have still not received it.
