MY LINE HAS BEEN HARDLOCKED

I have been a Vodacom Customer for the past 9 years or so. In December 2014, for the first time in my life, i missed just one payment, one payment for my contract number, which is the number that every person knows of. Now Vodacom, has taken it upon itself to hardlock my number. No incoming calls no out going calls. How dare this service provider is? 9 years of good service, then just one payment, then my line is hard locked. This is so hillarious, i can't believe this Company has done this. Right now, nobody is able to reach me. I have made an arrangement with them that i will pay this money at the end of this month and guess what? Hard locked, Really Vodacom, really? What is i am caught up in an emergency or one of my relative, my wife or children are in desperate need to talk to me, can you really explain this to me. I am so frustrated guys. Someone please stop this exploitation.
