TELKOM SA MESSED UP MY CREDIT PROFILE

I have a problem with telkom, my landline has not being working for the past 1yr 6 months, I've been calling Telkom to come and fix the problem and they told me that the area that I'm staying has a signal problem and they will send a technician to come and fix it and they never came. This happend for almost for a year and when I called them to inform them that the technician never arrived they kept on promising that the tech is on the way and my call has been logged and that never took place. They sent me a statement that I owe them and I told them that I'm not going to pay for the service that was not even provided. My husband called them and they asked him to send them an email mentioning how long was our line not being working, He sent them and they never rep**** us at all. Now this month I was going through my credit profile and I saw that they have listed my name on credit bureau Compuscan. I can not take this any more. TELKOM IS NOT A GOOD SERVICE PROVIDER AT ALL AND THEY CANNOT BE TRUSTED. I WILL NOT RECOMMEND ANYONE TO MAKE BUSINESS WITH THEM. YOU WILL BE SORRY IF YOU TRUST THEM BECAUSE YOU WILL HAVE A BAD CREDIT RECORD JUST LIKE ME. I'M DISGUSTED AND WILL NEVER EVER DO BUSINESS WITH THEM.
