Do you mean October 2011 or 2010? If you have a receivable still unpaid from 2010 - you should have contacted all those involved on the bill of lading and/or wrote that off at year end (depending on the amount).
If the receivable is from 2011 - make the calls to the consignee and/or shipper - if you haven't already gone this route.
Can you also please post the address and phone number of Trans Xline for other members. The more information you provide us - the better - perhaps someone else can assist you or is also trying to collect.
