MOVED HOUSE A MONTH AGO AND STILL NO LINE!!!!!

I moved house a month ago and requested my line be transferred. I have spent hours and hours on the phone each week and in store trying to get it sorted. They commit to times and dates and send sms's but no technician ever pitches up!!! I work from home and internet is vital!!! I haven't been able to do my job for a month!!!! Telkom has the WORST service in the world. On top of it they only disconnected my line 2 weeks after I moved and now expect me to pay for their mistake. I need my land line with ADSL!!!
