Are M Lhuilier and Cebuana Lhuillier the same? Short answer: No, they are not. If you are trying to collect money from one be sure you go to the correct Lhulier.
Long story: I had to find an M Lhulier near Alcoves as a guest who was staying 6 weeks had pera padala‘d to himself the amount which was supposed to be our payment. There seems to be more branches of Cebuana Lhuillier though so finding an M Lhuilier was a bit tricky.
The closest M Lhuilier branch I could find near Greenbelt was a bit of a walk – it’s in the Ayala MRT station. (So pass through Greenbelt, then Landmark, then Glorietta then SM.) Exiting SM you can’t miss the branch, it’s right in front of you as you exit the mall (on your left will be the rest of the station with the ticket booths, etc.)
Payment went smoothly but it took a little time (20 minutes or so) for M Lhuilier to cough up the money.
