Tekom very poor services

Telkom have installed a line for a 10 meg line that I have app**** for. The installation was on the 15th may 2018. From then until today I struggle to get a user name and password for this service. I called Telkom almost every day and logged an incident at It and every time I call they say it is an internal problem and have a backlog I must wait and call back within 48 working hours. Or they say I must hold the line and then just cut me off or they are offline when they don't know how to assist me.
