Prevent Insurance Companies from auto renewing insurance policies electronically

I feel that this is a bad practice. My email made no mention of the fact that the policy would be auto renewed. A fact only to be found upon downloading documents via a link in the text. Most people I have spoken to were unaware they had agreed to auto renewal at the time of inception of the policy, and generally they found out by noticing a debit from their bank account.I found that companies are profiting by charging disproportionate amounts for a few days cover when people claim a refund too.
