Telkom sucks

I have never known such bad service in my life. I placed an order for an ADSL Uncapped 4 MBPS line and internet connection ref no. ***a. The line was installed, but they gave me a capped 2 meg line which drops connection every 5 mins. I have called about 12 times and have been given the following:- it will be corrected with the next 4 hrs It has been correct - should be working by 4 pm this afternoon Has been done will receive an sms later today Cannot do the connection as there is NO DSLAM available at the exchange And Today - they installation of the line is still pending and they cannot give me an ETA *** - I get a different response from Telkom each and everytime I call them - which one is the truth - I am, still none the wiser - the Line has been installed - but today was told that it has not been done
