BAD SERVICE AS USUAL

I moved my DSL/internet over to Telkom from another provider in August'15. My email account/address suddenly stopped working over a week ago and I can not get it up and running, after five calls to Telkom. Each time I am given a different story or I end up with a 'dead' line that goes nowhere. How is it possible that a network with a majority monopoly can give one such poor service and get away with it. I can not get my emails and both private and business emails are shut down.
