Why must I struggle to Cancell this Policy???

I called Miway earlier so I can cancel this policy because I feel like I am not valued. The person who took my call, after making me hold for over 5 minutes comes back and says everyone is busy on the phone, (understandable)....What makes me unhappy is that she says someone will call me back within 72 hours, by Monday atleast???? WHY????? Is MiWay really that terrible in customer service? I want to cancel my policy and I want the process to be as easy as it was when you were bringing me on board!!! Please don't give me a hard time! I just want to cut my losses and go! Thanks!
