Fed up of VODACOM!

I am getting sick and tired of VODACOM!!! I refer back to my article (15 November 2018) A manager called me last night from Vodacom because of my complaint. He advised I should call my bank to hear why they reject my debit order. As he checked my account to see what really happened, he did and i called my bank. They are doing an investigation as it was authorised for my d/o to not go off to vodcom which never came from me. I called Vodacom again today to postpone my debit order date which will go off Tuesday 20 November and the double payment will go off. All vodacom could tell me was they cant change anything now. I want this fixed and someone to call me that can for once assist me correctly!
