Caller: Some mob called Offer Assurance, flogging deals on Internet packages etc

SO I then called the number, it gives an option to opt out
... press 5, then tell you your number....
then press one to confirm opt out... and
then BLOODY sh*tE their system hangs up without confirming if MY number
has been opted out or not .... Hmmm
So I should expect more pestiverious calls then hey? Grrrrrrr.

Hangs up when answering machine answers.

Annoying caller leaves. No voice message
