Forced phone insurance

I have recently upgraded and had to take compulsory “free” insurance from a third party otherwise Vodacom could not complete the upgrade. This after I said I have my own insurance I do not need additional insurance. I was then told the onus is on me to cancel the insurance after three months or I will be charged. Now that I am trying to cancel I am being sent from pillar to post and need to call alternative numbers/ third parties to process the cancellation. We are forced by Vodacom to take additional products we do not want and say outright no to and then they make it very challenging to get out of it. I have notified them again after the forced “free” period to cancel and not to charge me and expect them to handle it since the forced me into it as opposed to referring me to third parties ******! Greedy! Inconsiderate! Poor service! Care only about money and definitely not their customers
