Call Center Agent has **** to me

Good Day,<br> <br> I called the Telkom number: 081180 after noticing that I have been over charged for the past month. <br> <br> I talked to an Agent called Nkosikhona Mlaba after waiting for about 10 minutes before anyone could answer. The entire call took about 30 minutes. The agent said he could not help me as the payment had not reflected on Telkom's account.<br> <br> I then asked to speak to a Supervisor due to a lack of understanding / knowledge from the Agent. He told me that the Superviosor (Nkosikhona Msomi) will tell me the same thing he told me and never got the opportunity to speak to him / her.<br> <br> I asked for a reference number for the call and the agent said he cant give me one, but he will call back to provide me one. 24 hours later, I am still waiting.<br> <br> This is totally unprofessional and I don't want to sit on the phone for another 30 minutes just to be deceived.<br> <br> Who can help me with my query??
