Fiber line

I have had my fiber line installed just on a month and it is the 2nd time I have had a problem with the line in a space on 1 week. I have been a vodacom customer for over 10 years with my cellphones I have just spent over an hour on hold on the *** number without speaking to anyone. I'm at the point where I tell vodacom to come remove their fiber stuff and get it out of my house as they are suppose d to supply me with a service I'm paying lots of money for but does not work. They are in breach of contract. This is not the service I expect from them.
