Vodacom just don't care

I'm absolutely disgusted with the network, signal and service.

I'm on a business package and trying to run my business from my phone. I can never hear my clients and they can't hear me or I have no signal. I have been complaining about network problems. I was told to try different setting of which nothing has worked.

I have now emailed them as I'm tired of the signal problem and instead of trying to help me they just are sending me to different departments.
