NO CUSTOMER SERVICE

I upgraded and took out a new contract 2 years ago. I confirmed the contract over the phone in January and the new headset device was only delivered to me in mid Feb. Vodacom charged me for January and February, I refused to pay for Jan as I didn't have the new device. Fast forward 2 years of constant phone calls, emails etc, I have paid my contract agreed amount every month since my contract has come to an end, and I am on a month to month basis. I received an email on Tuesday to say that I owed ***xx amount and that I had 7 days to rectify it or my phone would be blocked, not even 3 hours after receiving that email did my phone get blocked! I have reference numbers from all my emails, calls etc over the 2 years but to call the call centre and explain the story, not once , not twice but possibly 4 times as you get transferred from one department to the other, is soul destroying and this has happed on numerous occasions. I was recently told to pay the amount and wait for an investigation so my phone could be reactivated and then maybe receive a refund from the outcome. I have been a Vodacom client for over 20 years and I am appaled at this service. My husband also had the worst service getting an upgrade special that was marketed by Vodacom on their website and then declined 3 times because they said the special didn't exist.
