Shocking service

I would prefer to award Vodacom no stars at all. I app**** for an upgrade to my contract in September 2023. They came to deliver my phone without contacting me prior and I was not there so they took the phone back. However, it shows on their systems that the phone was returned but they have never reversed the upgrade. I have phoned at least 17 times since September 2023 and they keep telling me that they will escalate the problem and it will be sorted in 24 to 48 hours. I have emailed customer services over 300 times. I have been told that I can't cancel my contract because it registers that I have an upgrade and my contract only ends in 2026. I suggest MOST people cancel their contracts with Vodacom as someone I know cancelled their contract which was costing them R2500 a month and now their cell bill with pay as you go is R400. Its worthy of a complaint in terms of the Consumer Protection Act. Which as an attorney, I intend doing as soon as I have time.
