No internet connection I am stuck with a router that's not working.

I subscribed to vodacom Fibre 5 months ago till this I do not have internet connection, I have called so many times spoken to 10 different consultants who have given me different excuses at the end of every call they tell me to wait for 42 hours and the matter will be sorted but that is not the case. Yesterday When I called to cancel my subscription they gave me the runarounds and what's frustrating is that I'm stuck with a router that is not working... It's hasn't been for the past 5 months and that's frustrating because it's blocking me from using other service providers who can do a better job then them.
