These jerks are calling and then after a few seconds are hanging up. Some dirt bag with nothing better to do is using someones money to make these calls all over the country. This LOOSER is looking up cell phone no. and using them for their entertainment. Find them or it and put them to work with an orange jump suit on.
Just call the number (401-424-4039), and ask them nicely to please take you off of their call list. Then if the person is nice they will tell you that you are off the call list. Then after giving them a few seconds, ask if you are now off of their list - this is important, because otherwise they might not really take you off. I did this about a week ago, and haven't gotten a call since! :-)
I hope this works for you! If it doesn't, just try it again, and maybe you will get someone nicer on the other side of the line.
