Who called from 3366

Got a call from the number 3366 by itself—no area code, no three-digit prefix. Left no message.

Just got a call from 3366, no area code or anything. I answered it and was informed that my debit card had been suspended, which, to my knowledge, isn't true at all. The message also said I could "press one" to be connected to a 24-hour help session, but that's all.

Same as Nate G.  call on my sprint cell phone from 3366 telling me to "press one" to be connected to their 24 hour banking hotline.
I don't have a debit card.

I received a call from 3366 a half hour ago on my Sprint phone.  I did not answer and they did not leave a message.
