Some Punjab asked for my husband, saw # on caller id. I said wrong #, then asked for address, said no. It was the same # who called before saying my windows computer was not working, when I told them it was an Apple they hung up. Scammers. Do not give them any information or acknowledge you are the one called. No and hung up. The area code is from California, which means its most likely one of those free Google phone numbers that cannot be traced to any one or any address.
