because my account is now garnishment and I have a letter from the plaintiff "SATISFACTION OF FINAL JUDGMENT IN GARNISHMENT" to me the account is pay in full?
It appears that the garnishee did not respond to the Writ, or otherwise a Final Judgment was entered against it. The Satisfaction means the matter was resolved as between the bank and the creditor. Your obligation remains, unless the money in the bank was sufficient to pay off what you owed.
