How do I leave?

I called in on Tuesday to cancel my car insurance as I am moving to another insurance. I was put through to another department on hold for 15 min then told there was no one to assist me. They would call me back. Thursday I called again having received no communication from miway - again i was placed on hold for 20 min. This is further confirmation that I am making a good decision to cancel my car insurance with you. Can I please be contacted to cancel my insurance.
