Same story here - Tried to call back and got busy signal. Blocked international calls on my cell phone and still received 3 more calls. Conatacted police to file a complaint - this should take care of it as I will file charges if needed.
I keep getting calls from this number once in the morning and several at night, with the same response no answer. I once picked up the call and they wouldn't hang up their end trying to hold me on the line, until I told them that I would report this number to the FCC, they then released the line. So I am telling all do not answer this call. I believe that if you are a true child of the King and your faith is strong, these calls come to test your faith.
I have my husbands cell phone, and were supposably calling him back for some school/training that he had requested... LIARS!!! My husband is the LAST person that would be seeking school/training at this time!!!
