Internet (ADSL) required but no service received

I have spent a total of about 10 hours on the phone back and forth to telkom. I called in requesting that they install and convert my telephone line to an ADSL line. I provided my details which at the time was incorrect and I was advised by that consultant that my new details have been updated and that a technician would contact me regarding installation. I waited a few days and received no feedback. I then proceeded to call the call centre (10210) to find out the progress of my request however, they could not confirm a date, I also asked that they confirm what my details are on the system, regarding installation and guess what? they got my details incorrect again!! SO I YET AGAIN asked the new consultant to update my details. The following day I took 2 hours out of my day to go and sit at the telkom menlyn branch to make sure everything was correct, Oh and what a surprise to see that my details were not updated!!!! She then confirmed that it's now correct and the technician was going to call me. Long story short the technician called the wrong number and went to the old address. 6 consultants later and nothing has been done. What pathetic service!!!!
