Very bad service from vodacom

Good day. Very bad service from vodacom george. I am paying my account every month at vodacom garden route mall. But inspite of all my payments every month my line is bloked. According to them i haven't paid my bill for november 2017. I have all my proof of payments and have been batteling since desember 2017 to sort out this problem. No one can give me an answer. My proof has been emailed to numerous people wish promised to sort out this issue but no one kept there promises. Now my line is bloked abd i told them i am given them 2 hours to get my line back on otherwuse i am going to the newspapers with this bad service. I am very upset because of this and is thinking if changing to another service provider. I would appreciate it if any body can issist me in this matter. MM Lotter
