Openserve technician no show 3 times arranging time and date

Openserve... I've ordered an upgrade through MWEB to a fibre line, the fibre line was installed on the 9th of October but there is a fault on the pole, they would have come out to fix it on the 10th of October, I've called MWEB and Openserve numerous time to find out what is going on, they are nog give any feedback and keep telling me they will escalate the problem, I have set a time and date 3 times with the technician to come to my house and they never pitched. every time I have to put in a days leave just to wait around for a technician that does not show up.
