Unfortunately globe changes its preterminarion fee last nov. 15 your payoff fee should be your total mrf multiplied to your remaining lock up unlike before nov. 15 the computation is your handset base price less your cashout (if with cashout) divided by 24 then multiplied in you remaining lock up.
Finally got some answer... The agents that I've talked to from November and December were all correct. The agents that I've talked to last January 9, failed to deduct the cash out that I've paid before acquiring the unit, that's why my pay-off fee increased.
As of January 22, 2014, my correct pay off fee is Php 5,916.67 and not Php 7,916.67. Thank you for all the replies. Finally got some closure.
