25 min holding waiting just to blacklist a Device.

I lost my device and wanted to blacklist it however i kept hearing the IVR over and over again for 25min and still there was no one answering the call to assist. Either the Agents dont give a damn or maybe as a service provider you dont care. I want to blacklist my phone!!! Is this so hard! Your online chat does not work either....You wait and wait till you are blue in the face...Not professional at all Vodacom.
