Who called from 2031291358

We also received a call after 11pm from 203-129-1358,
No one on the line, but 3 days later our phones were not working,
Anyone calling use got a busy and we could not get a dial tone, it
Just sounded like a open line when we tried to use it.
Our display said "LINE in use" , which they were not In use by us!
I called our phone company and informed the fraud department etc.
Seriously sick puppies out there!  Hope they get repaid for this!

Got a call from 203-129-1358 after midnight, hate night calls, no one at other end.

Ditto on Concered's comment above!
Exactly what happened to us. 3 days after our after 11 call our lines were busy for no known reason .
I called repair.
Then called Bell office and fraud report. Thankful for that bad gut feeling!
This IS a fraud attempt on innocent people!
The area code 203 is from Connecticut, USA
Hope these SICK puppies doing this get payback!

Called after 12am????  No answer.  Called back, number not assigned.

Returning a call to a number you are not familiar with is not a good practice, and can lead to BIG problems!
