Rang twice. Knew my name each time...asked "Is that Pat?" I said " yes, who is that?" She said a name I couldn't understand. I asked " who did you want...Pat who?" She said a name. I said that was not me. I got another call a few weeks later which went same. I said "This is second time this has happened. Was it you last time?" She said, with hesitation "Noooooo" . I checked and it was same number each time and I saved the number.
