Lack of after sales service

Fibre was installed in our home on Friday and the router delivered on Tuesday morning. Since Tuesday night my son has been dealing with at least 5 consultants with regard to get the router up and running. Not one of them were helpful, he had to tell them what should be done, they then said they'd get back to him and an hour later we had to WhatsApp them for the umpteenth time, still with no assistance as one can only communicate with them in that way. One of them said wouldn't we prefer to use our old router!!! Definitely not as payment was made for their brand new one. As they finish at 20:00 they were quick to fob us off and would get back to us which needless to say it's Wednesday night and we had to go through the same palava with no help at all. Very disappointing after sales service and those particular 5 consultants should go on a refresher course.
