Dear Chris klinton,
We have not heard from you in a long time and we are growing quite concerned. We have also been trying to contact you but to no avail. You have been patronizing our products for several years already and for that, we are truly grateful. However, upon reviewing our records, we found out that you have not yet sent a payment for your bill which is already 2 months past due. Perhaps you are just too busy at the moment, or you may just have forgotten about it. We already sent you an email and a letter regarding that, but we got no response. We have to ask you to pay at least the minimum amount of $267 within 10 days to save your account with SID Auto Supplies. Otherwise, it will be cancelled and collections will take charge. If you have concerns about this, kindly call me at 4445566 so that we can come up with agreeable terms. If you have already paid, just disregard this message.
