No feedback on cancellation

I took out a data contract from Vodacom that wasn't what the call centre agent claimed it to be. I cancelled soon after receiving the package. I was told that the package will be picked up in 48 hours and the contract cancelled. It is now two weeks later and nothing, despite me phoning on a regular basis about it. The call centre agents are extremely useless and cannot help. It does not help that the agents do not seem to work off a centralised system.<br> <br> As I am typing this I have been on hold to speak to a manager, but this in itself seems impossible. They have now taken my number for the third time to give me a call back, but I am not holding my breath.<br> <br> I find it strange that they are allowed to harrass consumers with sales calls but cannot do the simplest of things after sales...
