Registered Debt collector.
Executive level staff who kenar play ... have no where to turn to for actual help.
Next time, make sure collect pay on the spot before walking out of the office. Under MOM law, IIRC, pay issues pertaining to the termination of services have to be settled withing 24 hours, so a company saying have to wait till end of the month for accounts dept to do bla bla bla, you can just tell them that such a practice is breaking the law, and that they must settle within 24 hrs. Of course, make sure you have on hand the actual chapter and paragraph stating that law. Once they know that you know, less chances they will take a risk and fool around.
