Pretense at resolution of issues

Pretense at customer care. I complained, 1 person called me, with a promise to have my issue resolved soonest. I then called their customer care twice, each person promising to call me back and resolve the issue. Do date, no one has called me back, nothing has been resolved, I still await the 1st pwrson to resolve my issue soonest. The 1st follow up call was merely so vodacom could pretend to take complaints seriously without actually having to do anything. I need this issue resolved
