I got five calls within a minute and I dont answer unless I know whos calling me. I got a message but it sounded like it was outside some were but that might not have been but no one said anything at all then they hung up and called back untill I added it to my bad contact and set it to no ring tone and still the calls kept coming I turned off my phone for 5 minutes and when I turned it back on they stoped so far and its been two hours they called 9 times before i turned off my phone.
