iTalkBB vs IDT Global

I signed up for a TV streaming box from iTalkBB a few months ago, which was fine at first. But they recently contacted me out of nowhere and told me that I was responsible for a phone number sending out illegal spam messages! They told me I signed up for a phone number through them (I never did that). They told me I had provided a picture of my passport to them to verify my identity when signing up (I DEFINITELY never did that). Then they told me that the signup was from an IP address in China two weeks ago, when I haven't left the United States. So it obviously wasn't me, but they still were trying to tell me that I would be in trouble! They wanted to get my real phone number canceled, they wanted to involve the Shanghai police department... Just an absolute nightmare being put on me, when it was actually their own problem with allowing a fraudster to sign up. The whole call was very suspicious, like they were trying to scam me or get something out of me, although I can't quite figure out how. iTalkBB needs to get their security under control and not try to dump their own problems on their legitimate customers. If this is any indication, at some point their entire block of phone numbers might get blacklisted for allowing too much spam, which would not be fun if you were trying to use one for your own phone! You will probably want to stay away unless you like dealing with incompetence and bad security.
