Manager refusing to call a customer !!!!

I am having issues with my Vodacom fibre line for 7 weeks in counting! I have been calling the call centre almost every day to have the line restored. I have already logged 3 incidents with them of which the 2nd one was JUST CLOSED…. The 3rd one is open SR*** and is ALWAYS getting escalated, however no one calls me. Today I called in and had requested to be called by a manager in an hours time, as I need the line fixed today. The agent I spoke to named Olwethu called me and advised that a manager will not call me. How can I be refused a call from a manager? That is ridiculous. I have now resorted to logging a hellopeter request as I am fed up with begging them to fix something I pay for. I want a manager from Vodacom to call me and I want the fine fixed,ASAP!!
