You are so insistent on supporting and sticking up for the bad guys, I am wondering if you are one of them. Your English and grammar skills leave about as much to be desired as the callers we are speaking of, and you seem very annoyed over something that shouldn't affect you in any way. You can tell a lot about a person by the way they act and how they respond to different situations and you sir look suspicious.
Unwanted calls repeatedly come from 313 355 1170, they hang up, never answer and when called back report tooo busy to take call. No real way to stop them from annoying calls all hours of day and night. We don't know who they are and we don't owe them a penny.
