Called me 13 times. Didn't leave a message or anything. Blocked them.

I recieve the same call but with no v-mail. I simply block the calls.

I have received many calls from this number and they left voice mails. They usually call about 4 in the morning. I finally listened to the voice mails and they were people saying something about condoms. It was hard to understand. When I called back using an anonymous number (*67) it said the number was disconnected, yet I still get calls from them. Does anyone else get these calls?!
