Appalling service to customers after paid

The company was suppose to do decoder installation, my setup had Explora with extra View, instead of leaving the setup as is, they open a new account for me with Multichoice. Now have two account same amount 1. They never called Multichoice to notify or confirm what they were doing. 2. When i complain to them they keep on saying the notes says of technician, not wanting to hear my story. 3. Refuses to give me email of a person i ca escallate the matter to only gave me general email to support. 4. A disgusting signs that they are not willing to assist. 5. Talks of extra charge if they come and resolve as its its a different job all together.
