Can someone do something PLEASE!!!!

I signed up with Mweb and Vumatel in Dec. They came out on 13 Jan to install after numerous calls and there was a blockage so they could not completed installation. More than 5 weeks since their initial attempt to sort the infrastructure out and again numerous calls whereby you can't even speak to a human and I have to leave my number for them to call back, still nothing is done. Obviously my existing business and the new installation is not of any value to them as they make very little attempt to sort out the problems and complete the installation. But they happy when you pay them and they keep your money. Its been over 2 months since inital contact, please show some initiative.
