Got a call. No message left.

One lady, like a Spanish speaker, asked me, "Why do you take college classes and what is your education gold in USA as a second language speaker?
I asked very detail about her position and title of job, but she did not answer anymore and quickly hung up.

Called my cell at almost 1 am
shows call from British Columbia
When I call it back it has a recording that it is Luminous Solutions
when I googled the name it shows it is a Canadian based wireless dealer
