Account changed and now worse of than before

The problem started with internet connection dropping the line, there were four technicians that came out in a period of 3 weeks. The third technician said the problem was the username and that i must change it. I went to the Telkom office at Mall@Reds to have the username changed and the person that helped me there made one or other mistake and then my account had to be deleted and a new account created that resulted that i am now worse of because of the mistake that was made and that had nothing to do with me at all. All i wanted was to have the username changed. As a result of that where i was paying R788.60 plus vat and included in the price was 50GB of data. With the new account i am paying R788-60 and a additional R130-70 for 20GB of data resulting that i am worse of and not through my doing. I have logged numerous disputes to no avail and the lattes about a week ago with the following ipacman ***.This has been going on sines somewhere the beginning of DEC. 2015. Telkom is welcome to get the transcripts of conversation regarding this matter and then they will hear how customers are served just cut of three times in one day and with no attempt of calling back.
