Is there a worse "service provider" than MWEB in South Africa

I simply cannot believe the SHOCKING service from MWEB.I subscribed to them about 2 weeks back for a 40mb fibre line.The router etc was received timeously ,however ,I had to install it on my own which is impossible without help.Finally they assisted telephonically with this. Their signal has been extremely poor and have phoned them on SEVERAL occasions,at my cost for half an hour or more.They then arranged to phone me today at 12 and I am still waiting (12.25).I phoned them and they promised to get someone to phone me back immediately.I am STILL waiting. How does a company do business like this !!! I was on the phone with them for 3/4 hour and a further 1/2 an hour (the last 2 calls),so not prepared to wait any longer. I am going to cancel the subscription.
