6/9/22 at 12:52 pm call came in from "Unavailable". On my saying "Hello!" a female voice not identifying herself said, "You have received several notices by mail about extended auto warranty ..." and I hung up. Return call to 512 440 1842 got phone company recording that " the number you dialed has been disconnected or is no longer in service. ..." This is the 25th call received from a disconnected 512 440 number, each with different last four digits; and the second one today. True, frequent unsolicited and unwanted mailings offering extended warranty are being received; not one has the name of individual and company making such offer- only a phone number to call. - very suspicious!!!
