Pre recorded message from Severn Trent saying water supplies may be affected from Oct 20th for a week between 8am-11pm then quoted the website. I thought it was odd as number is London!

An automated call asking recipients to go to a specific website. If it's not a scam, fraud or other crooked call, I don't know what it is.
