I will never use this company again...I called to cancel my insurance and was told I had to email them a reason why and other stuff plus my policy started on the 13th of Sept...I paid $220 then, cancelled my policy today and they took out $218.99 off my debit card this morning for a monthly payment...When I called them I was told it would be at least 30 days before I receive my refund...
