Worst MTN customer service

So I decided to get a contract with MTN the beginning of the November month. I then did online application which was approved on the 5th of November.i received the device on 13th along with the sim. I had to call for activation and i was told that it will be activated within 2-24 hours. I waited for 4 days but still no activation done. I the decided to go the store hoping that id get get. But the guy at the store told me that there’s nothing he can do for me and that i had to call again. I’ve even sent countless emails complaining about the matter (ref #1 *** ref #2 *** ref#3 *** ). Im currently on the third week and im stuck with the device and unactivated sim and istill can’t get help. This is by far the worst service ive ever experienced.
