Worst Internet experience to date...

In November 2015 I signed up with this company for a 4mb uncapped internet service. Everything went well for the first couple of weeks. I had full 4mb download- and almost full 4mb upload speeds (which is more than Telkom can supply)...Until 3 weeks into my contract.....<br> <br> I work from home and my job is 100% internet based, a fact that I had constantly made the technical staff aware of. So no internet, no work.<br> <br> One morning close to the end of November, I woke up, only to find I have no internet. I called it in and it was sorted out within an hour, but only giving me half the speed I am paying for.<br> <br> I have since been yelling and shouting at staff memebers on a regular basis to get what I am paying for, but to no avail.<br> I cannot speak to anyone in charge, as they are always in meetings, in the loo or out of office. Everytime I phone in, staff members promise to call me back within 15 minutes, but NEVER do!<br> They have caller ID, so today my internet is completely down, it is now 10:30 pm, everytime I phone in, my call simply gets ignored.<br> <br> This is the worst service I have had to date.<br> <br>
