This is causing me STRESS

I find it very unbelievable how i am struggling with vodacom and there insurance company trying to cancel something is impossible with them it is almost like trying to leave a cult a few month back i spoke to a agent in the cancellations department called Mogosedi very unhelpful and just trying to sell more products the more i am trying to cancel at the end of the day i could not even get a ref number from him as he said they are not allowed to give one(I've been getting refs from other agents)long story short i had to call in again to get it cancelled and had to listen to another sales pitch. Then we have the insurance which I cancelled last year, it decided to just deduct premiums randomly from my account and the best part is when you try to get it back they have to investigate and other excuses of "backlog" and give you a time period of 30 days for a refund. Oh yes don't try and ask to speak to a TL that's not happening as they don't deal with the consumers.
