Dear Andrew Hall,
Please be reminded that your insurance premium of $80 for the month of June is past due. Your accident insurance is very important for you and your family, please do your best to remit your premium right away. In the possibility that an accident may occur after you failed to pay your monthly premium, you will not have coverage for losses or litigation. We will wait for your payment until July 10, otherwise, a lapse will occur. Do not endanger your family’s financial security by not paying your premium on time.
