Who called from 7862202114

I heard a beep when I answered and that's it - line was completely silent afterwards

Called back and got a busy signal.

This is a recording message selling insurance

i got several call over a period of 8 days, inclusive of late at night. I called back many times on different days and different times... always busy. This caller is very irresponsible and or fraudulent because legitimate businesses do NOT behave this way... all parties should be extremely careful with ANYTHING they have to tell or say; especially if they are offering INVESTMENT Services.

Called. I did not answer. They left no voicemail.
I get constant calls from numbers I do not recognize.
I'm tired of this BS.
