VODACOM INVADED MY PRIVACY

I had a U choose flexi 150 contract that I took out with Vodacom. Last year there was ********** activities with my bank account in January 2019. I reported the matter with my bank and I changed banks. I went into Vodacom store that Saturday 26.01.2019 and paid my monthly premium. February I received an sms saying I owed money. I called Vodacom and I spoke to this sweet lady I informed her of where the problem was and she informed me why I owed the R100(because of the BDO that was not received) I told her that I changed banks. She said to call another time to set up the BDO on my new account, I assumed she had cancelled the bank debit order as I was no longer using that account. That day or the following day I then went to the branch and paid the R100 penalty. I didn't set new bank debit order because I had 3 months left of my contract that should have ended in April. My next payment was April, I paid R702.00 as per their sms. Which should have covered 3 premiums Feb-April because my premium a month was R160 and a few Rands and that would be the end of my contract with Vodacom. After my payment I still received sms that I owed. I called Vodacom again to cancel my contract in May and spoke to numerous people and I was advised I still owed them money therefore I could not cancel my contract. I asked that I speak to the relevant persons who will advise as to why I still owed them money I was sent from pillar to post. In June 2019 I took this up with their customer care who was of no help. October last year my connection was switched off my number no longer worked during that time I busy arranging a funeral for my brother(I can even provide the death certificate), a cell number I had before I took out a contract with Vodacom. This year I am being harassed by VVM, Vodacom gave them my phone records and who looked for the most frequent number on my phone and sent them a message that I owed Vodacom. VODACOM INVADED MY PRIVACY!!!!! The nerve! You don't know my relationship with that person! How dare you. Was my contract with Vodacom or is it with the whole world???? When I this contract I didn't know I was putting up with this. They took the only way of communication they had with me and now they go look for me as If I am a ********. Still today I keep on contacting them via telephone an email VVM and Vodacom and they still cannot explain to me how the balance that they believe I owe them was accumulated. VVM tells me to contact Vodacom, Vodacom asks I visit one of their branches, at the branch they tell me the cell belongs to someone else and that my contract was handed over to legal they cannot assist. The treatment I have received from Vodacom is unacceptable and disgusting. I took out a contract with Vodacom which was R150 a month. I spend more on airtime than that. Can I get this sorted or do I have to continue to struggle like this?? Is this how you treat your clients? I am so angry and tired of having to call and explain the same thing over and over. If anyone knows of where I can report this company please let me know.
