Vodacom lacks integrity

My contract stated free 5GB premium mailbox. My contract only expires Nov 2022. Now they want R29 per month extra to keep my vodamail but can't even get it working. I have complained since last week Wednesday. They keep on saying give the team more time on Facebook messenger. Managed to get through to someone at call centre today by choosing upgrade option - yes all other options you get toby the robot. Nowhere is there any option for assistance with vodamail. They claim last week's case was closed. So there is no such thing as fair and honest dealing as they unilaterally change contract agreements and they lie, they do not provide any service let alone timeous service and they abuse their "power" as they have no accountability whatsoever
