Vodacom Fiber

I have requested a relocation 3 months ago on my fiber line. It has also been installed by my service provider, plugged into the router and everything yet I still have no internet. They have billed me twice on my current account and my old account. Nobody knows whats happening every time I call in. They also keep putting me through from fiber to accounts back and forth. Now requesting a refund and extremely difficult to do as well.
