Telkom not solving my prombem

I reported the problem I had on the 2nd of November 2015 even today is not yet solve Sibongile Malinga shes the team lead at Pretoria she promised to solve this problem but shes no longer working on it I tried to remind her by sending emails and calling their call centre but she doesn't come back. The problem was I have contract with telkom which gives me benefits of unlimited calls telkom to telkom mobile number but on the 2nd of November it charged me like I was calling other networks which this benefit doesn't apply I called them and explain my problem then the lady she was on a phone she opens a case and give me case number which is ***9 it was on the 2nd of November 11:43am. Maybe their delaying me until I give up.
