Billing Dispute

Telkom Customer service is very poor, I called just now to dispute my bill, I requested to speak to manager, the Agent was so rude and giving me attitude, she was not giving me chance to speak, when she placed me on hold to get manager for, she was gone for 30 Minutes, when she came back the manager refused to take my call, that manager stated that there will call me back, I told the Agent that I can not wait for the call from the manager, where by she was already gone for 30 Minutes. Stillagai. When I told her to tell the manager to take my call now, the Agent still place me o. Hold for 30 minutes, until my line go cut off. I still don't believe how Telkom Agents work with there customer, it is so u professional, and not tolaratable,. My you please, how do you deal with such issues, we pay for the product and service, but we are not respected, we are not treated in a professional manner.
