Vodacom yet again disappointed.

I have requested 4 days ago to cancel my insurance, the automatic response says they will get back to me within 48 hours. Still no response. I have requested for an end date to my contract, still cannot get answers. Vodacom is quick to sell but cannot provide service. Not surprised. Also cannot receive Smss I brought that to their attention, still no response.! As a business owner this is ridiculous. Will be escalating to relevant ombudsman as I am not the only client who is receiving dismal and appalling service.
