Harrasment

I was called numerous times that my account is being handed over from recording. When you press 1 to speak to a consultant the phone just rings.If you call the alternative number it does not exist. After speaking to numerous consultants last week and explaining that I do not have an account with Nasua Mobile and is living in Richards Bay and not in Brits they keep on harassing me about this. Every consultant promised to make a note but a few hours later you get the same call. Please can this people get someone that knows what they are doing to contact me and sort this out. Today I received 6 calls from them and its not even 13H00
