I have been trying to cancel insurance for 3 days

A consultant left a call-back for me with the cancellation service 3 days ago... no call. I called the number again 2 days ago but during this time when I was transferred I was put on hold for 5 minutes and then my call was dropped. I left a call-back request yesterday but have heard nothing. I have also cancelled some parts of my insurance online and was told that someone would call me. hasn't happened. So having to post a complaint online just to get some customer service is a bit silly. I have been covered by another insurance provider since 5 days ago and might still need to pay for those days with Miway due to this.
