Jimmy Johns Changed the tip amount on the receipt! Baton Rouge, Louisiana

Over a month ago I ordered Jimmy John's and had it delivered.  The delivery guy was in a hurry, because he had several other deliveries in the building.  I tipped a dollar, but the delivery driver changed the 1 to a 2, and the 12.25 total to 13.25.  He did not even wait until I signed it before running out to his next delivery.  I have reported it to the BBB, but they deny any wrong doing even though the receipt clearly shows the numbers were changed!  If you have ordered from Jimmy John's make sure to check your credit card/bank statements because you might be a victim too!
