quitting, who should I address this to?

I am currently working in A/R department. There are two team, team 1 and team 2, thus two managers in this department. My direct manager is out due to sickness, and her manager (general manager) is out on vacation.

only team 2 manager is in and the next upper manager is vice president,

I am planning to give them two weeks notice in writing regard quitting.

To whom this letter should be addressed to?
