WHAT KIND OF BUSINESS DOES THIS?

I have logged a call with Telkom 10th October, I then followed up a few times over the past weeks on the progress of the call, nothing happens, the call I logged was closed for what ever reason.<br> <br> My 4Mb line ADSL is very slow , yet Telkom does nothing to try and assist me. over time i accumulated many telkom ref numbers related to congestion, shift blame to my ISP , then eventually telkom engineers get in touch with me saying they going to try and fix the problem , then hear nothing from anyone afterwards , I ALWAYS HAVE TO CALL BACK TO GET AN UPDATE , still with no intention of fixing my line<br> telkom refs I accumulated listed below dating back to a year or two and i still have problems with my inconstant line speeds <br> 325CTK300115<br> 120CTK210115<br> 200ATK230215 <br> 213atk131014<br> 233atk1102<br> 85atk280515<br> 200atk230215 <br> <br> My latest reference number is 55btk031115, its been now over 4 weeks(1 Month) with slow inconsistent line speeds, <br> .. What do I do? Telkom really does not care about customer service. WHAT KIND OF BUSINESS DOES THIS?
