FED UP WITH SERVICE

I am loosing count of the reviews that I have written in the last 2 months. Earlier this week I managed to speak to someone from management about the problems that I am having with Vodacom, after the discussion they said that they would put in a request to have my contract cancelled WITH NO PENALTY FEES, and that I would be contacted regarding this. NO one has come back to me. on Wednesday a representative came to my home to check on signals problems etc. tests where done on my Huawei router which I am using as the Alcatel router (number 3) do's not work. When I try and contact the person involved I get a message I AM IN A MEETING and will come back to me. Still waiting. Everything is discussed over the phone, there is no emailing to give one something to fall back on in black and white, so in the end one has no proof of what actions have taken place on nothing to fall back on as proof as to what is supposed to be happening
