Upon the date fixed for redemption, if the irrevocable deposit has been made and the required notice of the redemption has been given, no further interest on the bonds or notes so called for redemption shall accrue. This subchapter does not relieve the issuing local government unit of its obligation to see that the holders of the bonds or notes called for redemption are paid in full on the date fixed for redemption. From and after that date, if the irrevocable deposit was made at the proper amount on that date, the holders of bonds or notes called for redemption shall have no rights against the local government unit except to receive payment from the deposited funds or from the local government unit to the extent of the moneys returned to it pursuant to section 8224(f) (relating to deposit and investment of moneys in sinking funds and other funds).
