Vodacom doesn't give a darn about customer complaints

I wrote a review in July 2017, regarding my data upgrade debacle, whereby I am being charged for a device that was faulty , returned and no longer have, and where I had been offered to have the upgrade reversed. Though I was told that the upgrade had been reversed, it has not in fact been reversed and I am STILL paying for a device I do not have. R Maart sent me an email on 07/08/2017 stating that my account would be credited with R218.00. I'm still paying R189 per month for a 2Gb data contract. Its ridiculous.
