Providing this documentation is fairly easy in this case even if you do have auto pay. Your previous bills are available online and they usually go back to 18 months. It will show you the full detailed bill and also show the payment being made. Outside of that information you can view the documents and receipts section online as well to see if it contains any of the information needed. At this time this is all the information we have available.
