Cancelation and insurance of vodacom

I have such a bad experience with Vodacom trying to cancel my contract and insurance. Trying to get hold of vodacom is a nightmare. And i emailed thecustomer service and two different email addresses in the insurance and got a manager from a vodacom shop to email them but still did not cancel my contract or insurance. Ultimately they cut my services and told me if i do not pay they will not activate my services. I ended up paying the outstanding amount just to get my phone services on again after 3 days of waiting.
