Non existing claims department

I've tried 3 time now to launch a claim and still NOTHING. You want me to blacklist a number thats already blacklisted. There were two IMEI numbers on the phone and only one can be blocked. I've sent the detail through 3 times and every time there is nothing on the system. When asked to speak to a supervisor I'm told that I can't. Stop claiming that you'll resolve it within 24-48 hours. I'm still waiting since friday 9h. After this nonsense I really feel like cancelling my contract with vodacom
