Disappointing customer service

I was called and asked to join Discovery Insure for my car. They sold me all these benefits and got me to agree to joining them, at that moment I too canceled my current insurance. 19 Sept 2020 I get my policy from Llewellyn Njozela and get told that I should send back any changes that need to be made before the end of month as my cover would start 1 Oct; which I did. 1 Oct 2020 came and I still hadn't received my policy but my account was debited. Some time passes and still no word so I call and speak to Brian Muir who said he'll personally sort it out. Days pass and nothing takes place. 6 Oct 2020 I call Brian and say I want to cancel my insurance with them and he says he'll get the cancellation department to contact me. 7 Oct 2020 I still haven't received a call so I call back and speak to his manager Chesclin who said he'll get back to me in 45 min - 1 hr, that was at 10:23. It's 14:16 and still nothing. I am beyond disappointed with this level of service received as I had really trusted them, but I guess they're like every other insurance company; they just want your money.
