Telkom is useless

I phoned Telkom this evening with my internet problem. After waiting for more than 20 minutes I was informed by one of their consultants that I do not exist on their system and that their is no evidence that I have a fibre account with them. This is after using fibre through Telkom for 2 months already and I have paid them for their services. She also informed me that I have to phone Vuma as they installed my fibre line. I then phoned Vuma and the consultant at Vuma informed me that they can see my line and that it is active. I have to phone my service provider Telkom. I then told them Telkom said the problem not with them and he said that what they always say to clients. I tried to phone Telkom again but to no avail. After another 30 minutes of holding on for someone to answer me, I was just cut off. Please can someone assist me in how to solve my problem.
