I had a call at 12:30pm today from a guy with a foreign accent saying he was from "Talktalk Online Support". He said they had tried to send me an important update last night that didn't happen. If I don't take the update I will not have any broadband, email or phone tomorrow. He got me to take down a number "AA88I426227", which he would explain later. At this point I told him I would phone Talktalk to check and I hung up.
