Who called from 7742836862

This was offering me a free trip if combined income with my partner is $50,000 & we are between 25-75 years of age.

There were 2 extra digits at end of number. They were 37.  

When I redialed it, a recording was heard saying number wasn't available.

I just got this call too.  So strange.  I didn't press "1" ... just hung up.
