Complaints about Phone Numbers862-220-####

I called a number.saying it was a way to talk to Facebook I was connected to someone telling me I get disconnected to call this number back (862) 220-4977 . I did get disconnected and had to call back but before I did I decided to go ahead and change my password and delete my banking information from my Facebook pay and I then called back. I told.the man what I did and he got irate aboute.doing so so that is when I disconnected my session and he hung up immediately. I since have changed all my password to my banking apps from another phone and put a virus and security scan on my phone .
