Caller ID said "Wireless Caller". Didn't recognize the number, so I didn't answer. They didn't leave a message. If they're a legitimate company, why isn't their caller ID more specific? Why wouldn't they want you to know who's calling? Scammers.
They called and didn't leave message. Tried to call number back and couldn't. The operator came on and said try again. It's probably a scam be careful.
