Arghhh - particle board strikes again.

I am no fan of metal hangers drilled into the countertop - just to likely to crack it, especially if less than an inch or so thick. However, epoxy by itself is no better.

My recommendation - sounds like the installer tried to properly support it but that environment is just too damp for particle board. I recommend getting a Countertop installation firm (your Search the List category) to epoxy it to the underside of the granite to provide a waterproof bond - but also to install wood (preferably treated, or at least hardwood if not treated) support pieces trimmed to fit the sink profile to carry the actual weight of the sink - installed so they actually pull the sink up tight under the countertop so the epoxy is basically just acting as a sealer, not carrying the weight of the sink.

Some installers use plastic hanger strap - a no-go in my mind, as plastic creeps an awful lot under prolonged load.

Sorry - failed to put in the $ part - minimum servicve call charge of commonly $150 or so certainly, and commonly more in the $200-300 range because of the limited working space and commonly having to disconnect plumbing and remove garbage disposal to get it properly in place, then rehook those.

Here also is a previous similar question with answer FYI:
