Vodacom don't care about customer service

I signed for a Fiber & VOIP service at the beginning of July. It took the Vodacom Service Provider 8 site visits and 6 weeks to provide me with a connection. Initially I only had Internet, after complaining they initiated a VOIP connection, which when I tested it only allowed me to make calls, not receive them. Over the past 2 months I've phoned ALL the Vodacom helplines requesting assistance. All the operators do is log the fault and advise me that someone will call me back. As of today 4/10, not a single person from Vodacom has contacted me. I'm on the verge of cancelling the contract which fortunately is a month to month.
