Site down, back up and all plugins lost

My site was down this morning, after waiting on chat for 45 in someone came online and told me he would resolve it.

It is now back online and all plugins have been lost. I spent fifty hours configuring those plugins which are the main purpose of my website and everything is gone.

Any way it could be restored?

first tech guy forgot to restore plugins.
second guy took care of it in a matter of seconds
