Phone lines do not work! Why have a call centre?

The most *********** company I have had to deal with. Can't get hold of them because their phone lines says that they are closed, yet their website says they only close at 10. They have sent out technicians who said they have fixed everything and metro fibre just needs to reconfigure my router which will be done in 10 minutes, a few hours later and still nothing. Can't contact them or anything, classic example of a company that has grown too fast and has not appreciation for customers.
