Shocking vodacom fibre service

My vodacom fibre stopped working on the 7th of december. I have called them about 3 times a day. Sent sms's, emails and even facebook messenger messages. All they do is give me a generic response. Everytime I call I get a different consultant. When I ask for a manager, they tell me that they are only able to contact managers via email. They keep telling me that the matter has been escalated. I have been able to find the following out: my service provider of the line is openserve. On there system it is listed as vumatel. For some reason they cannot manage to change this information. The result of this is that a direct call to openserve was pointless as they cannot do anything until vodacom acknowledge that they are the line provider. I have to pay them even though there is no service. And if I cancel this contract, they will charge me a cancellation fee of a few thousand rands. I have never felt so helpless in my life. I feel I am being bul****.
