TERRIBLE INTERNET CONNECTION,NOISY LINE & SERVICE!

I have had no Internet connection for the entire day. This happens often. Connection is extremely terrible since we have accepted this service for more than 2 years. Had so many problems logged regarding noisy line since Internet connection activated as well as lots of phone calls regarding connection. I am a regularly payer but the service I receive is disgusting. Had a technician here and he confirmed we require a new plug for our modem hence the connection. We replaced the plug and received a bill of over R600 for a technician being called out for nothing. ..he couldn't detect anything wrong!!! The nearest branch is Kenilworth and don't let me get started with that 'wonderful' branch. It is as if visiting home affairs or going to a government hospital....frustrated much!!!! I too had a technician come check the line...technician said it's fine and clear. I then checked when I got home...difference NONE!!!
