Being one of the subscribers who are "locked-in" to the crappy service of PLDT (the Philippines' former telco monopoly), I know too well how frustrating to get things done or fixed by PLDT employees. Take for example the decade long wait just to get our landline connected. Another is waiting for a week's time just to get your phone line repaired by their single repairman crew. Even just the mere application for a DSL service took them three months to accomplish.
Those three months entailed talking to their call center agents who are clueless of what to do or to supervisors who either who don't want to talk to you or don't have much authority, sending fax documents that they need which they either lost or can't read (maybe due to the poor quality of their facsimile). In a nutshell, dealing with PLDT employees is the quintessence of poor service; which makes me think that PLDT's only requirement for a job applicant is the ability to make a number of excuses to placate the customers and also having a numb ear for the curses of the customers.
