I blocked someone on Skype but they're still ringing me?

I got a call from a foreign man I didn't know and didn't have on my contacts, he rang a few times and then stopped. A few minutes later the same thing happened with a different man, so I blocked him yet they both keep ringing me.
I don't know them, they aren't on my contact list and I don't know what to do!
