No internet connection

Good day, we have been without internet connection since Thursday 19/11 till today the 25/11. After sending several emails and calling them. They have been promising on every occasion that it will be sorted out. We stressed the point of our children doing online exams and our one son doing his matric exams. Yesterday he missed out on his exams. It is also affecting our business.This is the reference (***). We also asked to speak to the manager Earl to no avail. I trust that you will be able to assist in resolving this matter.
