The scam going on is that they will either call and let it ring once,hoping that if you missed the call,you will call back and be charged for an international charge. If you answer, they will keep you on the phone where,again,after one minute,you will be racking up charges. Go to www.consumer.ftc.gov and search "one-ring"scams. I got a call as well,I just didn't answer and didn't call back.
Somebody calling me again and again and eating up my minutes. When i first answered this called, I felt somebody is calling with saved record. On call back nobody answer.
I don't know anyone in Michigan so I keep ignoring the calls. They call constantly and never leave a message. I called the number back and it said something about baby stuff so I hung up. Super annoying!
