It was obviously from a call centre as there was a delay connecting after I answered. Caller asked for me by surname (Mrs ....?) which hey pronounced completely wrong, I didn't correct her. She had a heavy accent and claimed to be calling from the Do Not Call register to inform me the number was register and I would not be receiving anymore telemarketing calls. The number has been registered with DNR for a long time so there was no reason for this call leading me to believe it was not legitimate. I promptly hung up!
