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.
Im getting non stop calls from this number and i do not answer. They also leave no voice mails. I looked up the number and saw the same thing about something that i did not register for. I got so annoyed that i did not answer at all and i just blocked the number.
I started playing a new game on my phone, In order to get free coins, I took a survey, apparently when you answer yes to a survey question it signals them to call you! This is just one of 3 calls I have received in the past week..... All related to the survey! I have learned my lesson!!!!
