Stuck on tarmac in Charleston after getting diverted. No water or snacks offered even after 2.5 hours.

Flying back from the Caribbean and my flight got diverted to Charleston from Atlanta and we've been stuck on the tarmac since 8:30.

No water or snacks have been offered and we haven't been able to leave our seats or use the bathroom for the past 30 minutes because "someone is coming to taxi us to a gate."

This is also after only being offered basic snacks and one drink service on our over four hour flight. Absolutely horrendous planning, service, and communication.
