I have had a . number of scam calls purporting to be from TalkTalk.as has a friend. They do not seem to address me by name but ask for the account holder or state there is a problem with my internet connection. They seem to be either out of area or from a phone number starting with 0235678**** .I have reported them to TalkTalk and banned them, but be aware and hang up or tell them they're scammers and they will ring off. TalkTalk say they are not their numbers.
