These are the numbers that keep calling me, all ring once or twice, not allowing enough time to be answered and when I call back they don't give out any information unless I give them mine first. Very very suss!!

Two ring spam... calling from 5 different numbers, 4 different states - dirty tactic to get around legal limits... or call centre incentives - either way just plain harrasment

Thanks to this site - I'm not going mad

scam

They just called. The phone rang twice, so there was no chance to get to the phone. I used the *10# service to find the number, and called back. Got a voicemail saying "your call is important to us", and then another voicemail came over the top (with the first recording continuing to play) saying: "you are the first caller in line", then they hung up. I don't owe anything, but even if I did, if they are debt-collectors, as stated by Cleo, why do they let the phone ring only twice when they call, and why do they hang up instead of speaking to me??? Bizarre.

ok guys just got a call from these people - like everyone they are muffled voices and limited noise in the background - caller states when I called back that it goes to his direct office - no surprise there - anyway this is who they are
