Vodacom "Customer Care" non existing

I tried to contact my office in Gauteng URGENTLY early this morning. No signal. No network. No information OR warning from our "dear ISP Vodacom". I then tried to contact a client in Gordon's Bay urgently. No network, No warning, Not even dialing!!! Later in the morning, I visited the nearest Vodacom outlet in Gordon's Bay. The lady informed me that the entire area was "off", apparently because of a "faulty tower battery?!?!?! I lost a business transaction because of this - a loss of R 159 375. There is NO way I can recover this loss. Vodacom needs to tell me how they plan to compensate me for this loss. since it was/ is because of their incompetence that I lost this income. Right now, I am considering taking the matter for legal counsel, and taking the relevant legal action against Vodacom. Can someone also please tell me with no delay how I can cancel my account /s with Vodacom and move to another cellular service provider?
