Lack of communication

There is absolutely no communication from Vumatel - infrastructure was put in place in my complex a month ago and my complex is "live". I ordered a fibre package through an ISP that cannot proceed to assist me if I don't get a response from Vumatel. When i contact your social media team on Facebook i get told that they will "advise shortly" then days pass with no answer. I need an answer as to when my unit will be connected - i also have to give notice on my current wireless package but i cannot do so when no one from Vumatel responds. Sales people from VOX promised residents in my complex that if they sign up with them they will be connected four days later - it is now 9 days later and still no word from Vumatel
