Mtn-Shocking Customer Service

I am a Unisa student.I just had the most shocking customer experience my entire life.The issue was with my Study Data that was allocated to an incorrect number.Even though I had clearly indicated my new Mtn cell number where it was supposed to go to,when sending an sms to 44304 with my details.My query was not resolved.I spoke to almost six Consultants,being passed back and forth from Prepaid to Contract department.The attitude I received was shocking.They were all rude ,arrogant,I wonder where Mtn finds their employees.I will never be an Mtn customet.I am throwing away my sim card.Awful,pathetic,shocking customer service.
