Telkom are useless!!!

I have officially had it with Telkom. I have given them 3 weeks to sort out my issue and still nothing. <br> We upgraded from a 2MB 10GB line 3 weeks ago to an uncapped 4MB line. You would think that the line would be faster and more reliable, especially since we are paying double what we used to. Since the switch, which was meant to take 48 hours to stablise, the service and reliability has been shocking. Internet drops every 5 to 10 minutes, which results in us having to reboot the router. Technician came out to 'fix' the line last week. When he left, he closed the fault advising that it was fixed (which it isnt) and once gone, we discovered that our landline wasnt working. How he managed to break a landline by trying to fix the adsl is beyond me. I have been calling telkom since yesterday, have received nothing but empty promises, being put on endless holds and this last call, a snotty and rude agent who told me that there is nothing to do but to wait 48 hours for a technician to come out to me (who has not yet even been assigned to my fault yet). I have requested call backs from managers the website which haven't happened. I am ready to cancel EVERYTHING now, I am SO done
