Not delivering what we're paying for

We're paying for a 4 Mb internet connection, but it only connects at 2 Mb and is incredibly unstable. There is no response at their call centre after holding for over an hour 2 days in a row.<br> This is not the first time this has happened as our internet used to work as it was supposed to at a time, although only for a few days and then Telkom *****ed that up too.<br> Over the last number of years it has been an on-going struggle with Telkom to get our internet working properly involving numerous faults reported, unacceptable wait times and having fault cases closed without anything being done to resolve the problem. 1 example: I reported a broken wall jack in our house, and fault was closed and needed to be re reported and escalated 5 times in 2 weeks before someone finally came out to replace the faulty plug.<br> <br> At the very least, I'd expect them to do as they promised and are paid to do, if not, they are then committing theft and should be treated accordingly.
