Incompetency and inconsistency

I upgraded this morning at around 11h00 and the new phone I bought (Samsung Galaxy A3 Smartphone) required that I should do a sim swap, which I app**** for at the same time I did the upgrade. I waited for my new sim card to start working from around that time up until now. I called MTN Customer Care from around 13h00 with no success, I held on the phone for 15 minutes and more at a time before I got through, with no assistance from the consultants. My sim card is still not active! Only now at after speaking to 5 different consultants I am told that I can only be assisted tomorrow as the Department works 8-5!How ***********! I want my phone to work now! How can an ordinary sim swap take you more than a full day and night to activate? It is unacceptable, your customer service leaves a lot to be desired, I now suddenly regret why I did this upgrade in the first place, sort this mess now! Worst part is that the 162MB I had prior to the upgrade is gone, I want it back! Sort this mess out please.
