Go back and remember that Bank X (the ORIGINAL creditor) reported your last delinquincy in July of 2012, and you then received the collection notice in July of 2016. The collection account will fall off of your credit report 7 years from the date of the LAST DELINQUINCY reported by the orignal creditor + 180 days. In this particular case, this would make the collection fall off of your credit report in January of 2017.
