Installation of fibre by Vumatel not completed

We recently selected Vumatel as our fibre installers. Delivery and installation of the line was done promptly, however since this has been done we have been struggling to activate the device. We contacted Telkom, who through their friendly service tried to assist us, but they soon realized that we needed to contact Vumatel again as the issue could not be rectified by Telkom. We contacted Vumatel to which they soon realized that they had not completed the installation and that a technician still needed to visit the premises finish the installation. This conversation was had with Vumatel the last week of January. It is now approaching the end of February and still no sign of assistance has been provided by Vumatel. The service has been so appalling to the extent that we were contacted by Vumatel this morning offering us an installation of fibre at our home, meaning that Vumatel themselves are still under the impression that we do not have a contract in place with them. We are now in a precarious position where we still have an ADSL contract running (which should’ve been cancelled by now, as we now “have fibre) and a pending debit order from Vumatel with no internet access. Could this be rectified in promptly.
