Horrible Experience with Telkom Customer Care and Telkom Office (Sandton City & Rosebank)

Horrible customer care service ever found. 3 months back, customer care confirmed the change of plan and even after that nothing changed. Went to Sandton City office, they cant do anything - sent me to the office in Rosebank. Lady in Rosebank says, they cant do cancellation of service on the account, I will have to login and do it. Cant login, since the password expired. ring to reset the password, the screen is rolling rolling for past 15 mins.
