Vodacom "too big to care about the individual customer"

Vodacom decided to change the date they debit my account for my contract on. After many months of debiting on the correct date, they took it upon themselves to change the date. Without my knowledge or permission - breach of contract. The debit order bounced (I am not wealthy). Heard nothing from them until one day I received a sms saying they are suspending my account. Within 5 minutes it was blocked. Like a hard block - my phone and apps (including my banking app) are useless unless I am on WiFi. I go into a big Vodacom shop to try and sort it out. I explain what has happened, and the employee says to me (I kid you NOT), "Vodacom has gotten too big to care about the individual customer like you anymore." I was stunned. I again explained what has happened and the response was, "They just want you to pay and then you will be sorted." Now, I have been a loyal customer of Vodacom for over 20 years - I told the guy this too and the response was that they don't care about that. Again, stunned. So, I left the shop (still with a blocked contract) and a few days later received another sms saying that I will now have to pay reconnection fees on top of everything. Honestly, it does seem like they have grown too big to care about the individual customer anymore. My contract (or lack there of currently) is up for an upgrade. I will be cancelling my contract and all dealings with Vodacom and be going to another service provider. Maybe they still care about the individual customer. I am shocked and disappointed.
