Left in the dark. Terrible assistance.

More than a year ago, the builders cut off the fibre cable underground while working on the pavement. We contacted Vodacom to repair the openserve line and they only did it temporarily above ground as they were waiting for the cable before repairing it underground again. A few months passed and nothing happened. About a month ago, the gardening services cut off the temporary cable and again we contacted Vodacom to send openserve to repair the problem and explained that the whole cable needs to be repaired underground. The technician came, fixed it temporarily above ground and advised that the builders need to install a new cable before he can come and fix it. We contacted the builders and they advised we need to arrange a fibre technician to be present while this happens. We once again called Vodacom to log a ticket, but each time the ticket gets closed and no one comes out. We phoned again and they advised they have their own team who will dig the whole and install the cable, but so far no one is coming out to install the new cable. WHO DO WE CONTACT TO SOLVE THIS ISSUE ONCE AND FOR ALL???? We are seriously going to look for a new provider as this is just ridiculous.
