The level of customer services provided is scary

I am honestly sick and tired of Neotel. Our company, Profile Corporate Services had an account with Neotel up until February this year. We have had a horrifying experience with Neotel since September 2013. <br> <br> In September 2013 Neotel added a voice other charge to our account without our permission. Ever since then Neotel has failed to rectify this. I have lodged two hello peter complaints and each time it runs to a dead end and once again the people from Neotel goes silent.<br> <br> Our Account Manager Landa Jacobs have given us absolutely poor service and she never responds to my emails anymore.<br> <br> Please give me an email address of a complaints department or a Senior manager because the staff under then has failed to provide any service whatsoever and we are FED UP.<br>
