Who called from 2132102466

Called my cell phone. I always reject calls I don't know. No message left.

they called and offered a free cruise saying I stayed in their resort. This is definitely a scam

Hung up immediately upon connection. When I called the number back, it goes to nowhere.

Went to voice mail and they hung up.

Looking for info on this number. Called this morning. Caller ID showed "UNAVAILABLE". My call blocker blocks "UNAVAILABLE" ID's automatically, so the call never went through and there was no opportunity to leave a message.
