Network connectivity always a problem

I have been struggling with the no network connectivity for a week and a half. I’ve been calling them and all I get is that the tower is down and they don’t know when connectivity will be restored. I have been paying for service I am not receiving, instead I have been buying data from Vodacom just so I can get to connect to the internet which I find to be unfair. I want to cancel the services so I can move to a service provider that can actually provide me with the service.
