At 1256 PDT, today, Friday, 2008-07-24, I was called; the Caller-ID said the calling number was 510-564-2358. Neither the Caller-ID, nor the caller offered any identification and refused to provide it when I requested it.
The call offered "Extended auto warranty coverage."
I informed the caller that I was on the National DNC list and to take me off of their call list and NOT call again. The caller refused to acknowledge my request.
Five minutes later (1301 PDT), I called back and was informed that the number was disconnected.
At 318,326 miles, my 1981 Isuzu P'up diesel gets 33-35 mpg and is running strong; I won't want "extended warranty coverage" until I hit 500,000...probably about twenty years from now.... and not from these scammers!
It appears that this is an illegal telephone solicitation or it may be a hoax call (no worthwhile product) trying to determine which homes are unoccupied, as a setup for burglars.
