Vodacoms Useless service again, 4 weeks in a row to get 1 contract

Im gettting really annoyed and frustrated with the service from Vodacom, i have actually reached a point of such frustration that i am going to post this damn review on all social media platforms, Vodacoms customer serivce is the hight of uslessness, My contract was approved after me making a 1 million calls to Vodacom, i got a call from their confirmations department, i was asked 5 verification question: i answered all the questions, i was then told i failed the authentication because some of the answers was not correct, i was asked to call customer service to get the correct answers and "Condirmations" will call me back in 24hrs(24 hrs in this day and age" so i called ***, i was asked the same 5 questions which i answered. The agent was able to log into my profile , using the same damn 5 questions and answers i gave?????!!!!!!, so i aasked the agent what whats the way foward? I am at a loss here really, either i cannot articulate the requirement here or vodacom cannot, and last time i checked i could articulate any requirement quite well. Vodacom your systems and processes are are light years behind, The customerservice agent cannot understand why the confirmations agent is not accepting my answers (Same question same answers" to both individuals????? so the common factor here who is messed up is Vodacom, I have never in my life dealt with such flippant cusotmer attitude in my life, im being genuine when i say this, your service agents are so lax about cusomter service its laughable at best.
