Im trying to replace my faucet sink in my bathroom the bolts wont come off ! I tried using the wrench I have but it wont turn what can I do? is there another tool I can use
Yes, it is called a torch. A pencil torch, a regular berzamatic torch. Either will work. They cause the metal to contract and expand loosening the bolts.
The nuts that you need to remove are under the sink on the bottom of the faucet. Sometimes if they are corroded it's easier to undo the water lines and take the sink out and turn it over to get to them.
There are special tools made for that available at any good hardware store, they are like a deep-socket with a T-handle, but to help without that tool spray the bolt/nut/washer with WD-40 and let set for 10 minutes, wipe off excess and try again.
The tool is called a basin wrench. Sometimes they can be on very tight and or corroded. I have had to cut some off.
