They never give up. Must be vigilant..
In Australia we have a telephone scam on the go at the moment.
A guy rings your office or home and tells you he is a telephone technician.
He asks you to perform a very basic telephone check.
All you need to do is press 90# on your touch pad. He tells you all is ok. You hang up.
He know has access to your phone line and makes overseas calls, calls to 1800 lines etc. etc. You pick up his bil for time on your line.
It appears that 90# is a telephone link/reverse charge access capability that technicians can use to get back to their base or check faulty telephone lines.
Some sh

t has worked this out and is having a ball over here.
Good luck with selling your Vette to a genuine buyer who turns up and drives the Vette and passes over a deposit.
