Blocked for enquiring about Vodacoms incompetence

Once again the usual suspects! I had to phone in numerous times to cancel my contract. I phoned in numerous times to upgrade, then I called in numerous because poorly trained employees dispatched the incorrect phone. I then called in numerous time to ask for a reversal of monies because my bank account was debited. I thereafter called in many times to explain the entire process to your employees and how this ALL unfolded and finally the last lady understood after much deliberation. I am now at a point where I want to do a sim swap, I get a stupid automated voice note saying my number is blocked because I called in far too many times....Wait sorry, I'm trying to make your *********** crew competent and you now want to block me. Vodacom instead of improving its services, you guys make life so much more difficult. What do I do??
