When it comes to service problems, it has been my experience that the megacorporations are the ones which are most frustrating to deal with. With small businesses, you can find the owner and complain directly and the owner usually addresses your concerns as quick as possible. With megacorporations, the big fish are always out hobnobbing with fellow millionaires (and billionaires), with no way for us mere mortals to contact them. All we get to talk to are grunts who don't really care about complaining customers because 1) we're just one of the many many complainants they talk to every day and 2) we can just go screw ourselves and transfer to their competitors because they will still get paid and new subscribers will take our place. In short, they don't care about losing our business.
PLDT is one such company. And this is a long rant.
When we transferred to a new apartment building last year, I applied for a new PLDT landline service. I had been a subscriber for years and although our previous landline phone occasionally had no dial tone, the PLDT branch was just a five-minute walk from our house and having the problem fixed was easy. As for the bills, I was never behind in paying them.
