Vodacom Insurance not answering my calls and email

Dear Hello Peter, I have been trying to get hold of Vodacom Insurance since December 2019 to cancel my cell phone insurance. I would call the number *** almost every day. I recently went to a Vodacom Shop to enquire on an alternative number I can reach the insurance company on. The consultant advised they also struggle to reach them, sometimes it takes more than 30 minutes for someone to answer. I asked the consultant for an email address. I sent an email to Vodacom Insurance 2 days ago, and I haven't gotten any response. I wrote a review last year about the bad service I was getting from Vodacom's customer centre. I am still getting a terrible service and I am really frustrated right now.
