Vuma sucks

So far i have received shocking service. Firstly they never did a pre inspection before the install, then when they did come they had a reschedule due to them not having everything they needed. Then after a week of me trying to get a new install date (if i didn't ask it would of never happened) they made a new date. When they came the second time they again didn't have the equipment to do the job and wanted to reschedule the install once again. I managed to get them to install the line that day and they promised me that everything would be working and i would get a number to continue with the setup. This never happened due to there being a problem with the line. To find this out a also had to contact them and query this. They clearly didn't do what they needed to do to confirm if everything was good. Vuma please tell me what you would like to do about this?????
