Scam??

So I got a phonecall on my landline from someone stating that they were virgin media. They asked me to look up "my 1p country 66.249" which I stupidly did. They said they'd have to get me a firewall but as soon as they said that I hung up. There was a call centre in the background and the guy sounded indian in nationality. Was this a scam? Did I do something wrong?
