Very angry customers

I'm Johan Malan, got retrenched last year,because of my age i know it's going to be hard to find work again, so i went to vodacom to cancel my contract ***), i gave them the retrenchment papers and even pay the amount the guy told me to to terminate the contract, he told me it's canceled no problem. But it was not done as vodacom still want my monthy payment, but seeing as i dont have work and have no money in my account they black listed me and i cannot use my number, i can't recieve or make calls. I did everything they told me to do to terminate my contract, why is it not cancelled then? Why must this be my problem? I'm discusted by vodacom, I'm an elderly person that cannot pay. Im DONE with vodacom
