No installation and no action taken

I have signed up for fibre via afrihost 3 weeks ago. my status says pending site survey on my vumatel online profile but no one has contacted me yet. I have called vumatel several times and and they keep saying I just need to keep waiting for a call, I have not received any call. Finally they tell me to call britelink but the number doesnt exist. I have messaged them on Facebook, posted on their wall, emailed ********** and still no one is getting back to me. I really would like to move forward and not complain but nothing is being done. Kindly resolve this by calling me and setting up an installation date and time
